The reliable way to create a searchable database in WordPress is to model every record as a custom post type, store structured values in custom fields, use taxonomies for controlled categories, and then choose the right search or filtering layer. WordPress core can handle simple content searches; SearchWP adds field-aware, relevance-ranked indexing, while FacetWP adds interactive filters. Build the data model first, then connect the search experience to it.
Start with a record schema, not a search box
Decide what one database record represents and what users must be able to find. A book catalog, member directory, property listing and product catalog can all use the same WordPress pattern, but each needs its own fields and filters.
Define the record
Choose a singular record type such as book, member, property or product. Give each record a title, description and status, then list the attributes that must be searched or filtered.
- Book: author, publication year, ISBN, language and genre.
- Member: name, organization, location, role and membership status.
- Property: price, bedrooms, postcode, property type and availability.
Separate fields from taxonomies
Use custom fields for values that belong to one record, such as a year, identifier, price, address or status. Use taxonomies for reusable, controlled dimensions such as regions, topics, genres or categories. This separation makes filters predictable and prevents every value from becoming an unstructured text string.
#1 Best Overall
Create the custom post type
A custom post type gives each record a manageable WordPress object with its own edit screen, archive and query surface. Register it in a plugin rather than a theme so the records remain portable if the theme changes. WordPress gives the same recommendation in its developer documentation: put custom post types in a plugin rather than a theme.
Code or a visual tool
Register the type in a small site plugin when you need version-controlled settings and a portable implementation. If you prefer an administration interface, Custom Post Type UI and Advanced Custom Fields are commonly used to create post types, fields and taxonomies. Whichever route you choose, use one stable post-type key and keep it unchanged after records are published.
Set the search-related arguments
Make the post type public if visitors should browse it, expose an archive if you need a listing page, and ensure it is included in search. A post type excluded from search will not be indexed by default by systems that rely on WordPress search visibility.
Add custom fields and taxonomies
Custom fields
Create fields with a defined type and consistent storage format. Store a year as a number, a price as a number, and an identifier as text. Decide whether an address is one field or several fields such as street, city, region and postcode. Consistency matters because filtering compares stored values exactly or by numeric operators.

Taxonomies
Create a taxonomy for every controlled filter dimension that users may reuse across records. A region taxonomy can contain cities or service areas; a topic taxonomy can contain subject categories. Taxonomy terms are easier to manage and query than comma-separated values in a text field.
Enter representative records
Add enough varied records to exercise every field and term before building the public view. Include records with missing optional fields, multiple taxonomy terms and values at the edges of the ranges users will filter. This exposes display and no-match problems early.
Make the records eligible for search
Check the post-type settings for an option labelled Exclude From Search and leave it disabled when records should appear in search results. Also confirm that the records are published and that your search or indexing tool is configured to include the post type. An apparently empty search can be a visibility or indexing setting rather than a query bug.
Build the results view with WP_Query
WP_Query is WordPress’s code-level mechanism for selecting a post type and applying taxonomy and custom-field filters. Set post_type explicitly instead of relying on the current request, and pass the current page for pagination.

The following example lists books in a selected genre and published from 2000 onward. In a real form, build the taxonomy and meta-query arrays only when a visitor has supplied those filters.
<?php
$paged = max( 1, get_query_var( 'paged' ) );
$query = new WP_Query(
array(
'post_type' => 'book',
'post_status' => 'publish',
'posts_per_page' => 20,
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'genre',
'field' => 'slug',
'terms' => 'history',
),
),
'meta_query' => array(
array(
'key' => 'publication_year',
'value' => 2000,
'type' => 'NUMERIC',
'compare' => '>=',
),
),
)
);
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// Render the title, fields and link for this record.
}
}
wp_reset_postdata();
?>Use tax_query for taxonomy terms and a meta_query for custom-field comparisons. After a custom loop calls the_post(), call wp_reset_postdata() so later template code returns to the main post context.
Rank #3
Design the listing for no matches
Show the active filters, a clear no-results message and a way to remove filters. Keep pagination tied to the filtered query, not to the unfiltered archive. If a search term and filters are combined, make it clear which conditions are active.
Choose the search and filtering layer
The best choice depends on whether visitors need simple keyword lookup, field-aware relevance or interactive multi-filtering.

|---|---|---|---|---|
| WordPress core search | Titles, excerpts and content in searchable post types | Basic keyword search; custom filtering requires your query code | Lowest setup burden; no separate search index to configure | High when the post type and fields are implemented independently of the theme |
| SearchWP | Titles, excerpts, slugs, content, custom fields, taxonomies, comments, users, PDFs and selected additional sources | Configurable relevance weights, selected post types and custom forms; it is primarily a search engine rather than a faceted interface | Requires indexing and re-indexing when indexed data or settings change | Depends on keeping the post type and field definitions portable |
| FacetWP | Post data, custom fields and built-in or custom taxonomies | Interactive facets for multi-dimensional filtering; a Search facet can use a SearchWP engine | Stores facet data in an index table and re-indexes after configuration changes | Works with custom post type listings, provided the data model remains consistent |
| SearchWP plus FacetWP | SearchWP’s expanded sources combined with FacetWP’s listing data | Relevance-ranked keyword search plus interactive facets | Maintain both integrations and re-index when either indexed configuration changes | Most capable, with more configuration to maintain |
Use core search for a straightforward catalog
Core search is sufficient when visitors only need titles, excerpts and content across searchable post types, and your filters can be handled by a small WP_Query. It avoids an additional search layer and keeps the implementation simple.
Add SearchWP for custom fields, PDFs or relevance control
Choose SearchWP when important terms live in custom fields or taxonomies, when PDFs must be searchable, when only selected post types should be included, or when relevance weights and custom search forms matter. Its configurable sources can include custom database tables in addition to standard WordPress data.
Add FacetWP for interactive filtering
Choose FacetWP when the central experience is a listing that visitors narrow with several controls such as region, price range, status and topic. FacetWP facets can filter custom post types, custom fields and taxonomies. Its documentation describes indexing as storing facet data in a custom database table: FacetWP indexing documentation.
Combine them when both jobs matter
Use the SearchWP and FacetWP combination when users need a relevance-ranked keyword search and simultaneous, interactive filters. FacetWP documents built-in SearchWP integration, including Search facets that use a SearchWP engine.

Search extensions do not automatically understand every new field or storage change. After adding fields, changing which attributes are indexed, altering a post type’s search visibility or changing block-based storage, rebuild the relevant index. If results are empty after a configuration change, verify that indexing completed before debugging the template.
What to verify after re-indexing
- A record appears when searching its title.
- A distinctive custom-field value returns the expected record.
- Taxonomy terms produce the correct filtered set.
- Changing one record updates its result without leaving stale data.
- Pagination counts and result pages match the filtered query.
Test the database before launch
- Schema: Every required field has a defined type, and taxonomy terms use consistent spelling.
- Visibility: The post type is public, published records are present, and Exclude From Search is not enabled.
- Queries: Test keyword-only, taxonomy-only, field-only and combined searches.
- Empty states: Confirm that no-match searches explain what happened and provide a reset path.
- Pagination: Check first, middle and last pages after filters are applied.
- Permissions: Verify that private records and fields are not exposed to visitors who should not see them.
- Mobile use: Make filter controls reachable, understandable and easy to clear on a small screen.
- Index freshness: Re-index after configuration changes and verify newly added or edited records.
A practical architecture for common databases
Small directory
Use a custom post type, a few fields and taxonomies, then query the records with WP_Query. Core search is usually enough when visitors mainly search names and descriptions.
Large catalog with field-aware search
Keep the same post type and schema, add SearchWP for custom-field and document indexing, and define which sources contribute to relevance.
Directory with many simultaneous filters
Use FacetWP over the custom post type listing. Add SearchWP as the engine when visitors also need keyword relevance across fields or documents.
