Note: This is a living post that I’ll update as I go on in my quest to improve WordPress search
Version 1.2 - Added review of Relevanssi Search Plugin Version 1.1 - Added screenshots of Better Search Plugin
Search is very basic in WordPress so I’m trying to find some better solutions. In particular I have the following goals:
- Improve overall search quality and ranking.
- Be able to index specific content. Apart from jus pages and posts I would like to index PDF files and specific woo-commerce products.
- Suggest specific content for individual keywords. More or less as if I had an Ad-words campaign on my internal search web search. This is important to propose suggested editorially curated search results before those arranged by the search ranking algorithm.
To start I look for well-written articles on the subject of WordPress Search.
This is what I have found to date:
I imagine there can be at least three approaches to improve WordPress Search:
- a WordPress plugin;
- a third party service with a plugin;
- an integration with some software outside the scope of WordPress.
To start I have tested the following plugins:
Better Search – this is the search plugin I tested actively on this website. It is definitely better than native WordPress search although still quite basic. Here are some screenshots form it’s options and the results page;
- Automatic: Once activated, Better Search will automatically replace your default WordPress search with more relevant search results
- Seamless integration: Search results are perfectly integrated into your theme without the need for custom search templates
- Relevance: Search results are automatically sorted by relevance. You can also turn off relevancy based searching, in which case, results are sorted by date
- Control the results: Fine tune the results by changing the weighting of post title and post content. Turn on BOOLEAN search to override the default NATURAL LANGUAGE search of mySQL
- Popular searches: Find out what visitors are searching for on your blog. Display a list of popular search terms (daily and overall) on your blog in the form of a heatmap. Widget support for easy integration in your theme as well as a shortcode [[bsearch_heatmap]]
- Customisation: Support for a template file for perfect integration into your blog template. Alternatively, just input your own CSS styles in the Custom Styles tab in the Settings Page. Check the FAQ for more information
- Supports cache plugins: Works with caching plugins like WP-Super-Cache and W3 Total Cache
- Profanity filter: Customise the list of stop words that will automatically be filtered out of search queries
- Translation ready: Better Search is translation ready
Relevanssi – A Better Search – this plugin is currently active on this website. Respect to Better Search it creates an index rather than scanning content at runtime. It has many options available in the free version. For example it allows to establish the weight of elements so you can decide how much a hit in a title counts weighs more than than hist elsewhere. You can even decide not to index titles at all.
- Search results sorted in the order of relevance, not by date.
- Fuzzy matching: match partial words, if complete words don’t match.
- Find documents matching either just one search term (OR query) or require all words to appear (AND query).
- Search for phrases with quotes, for example “search phrase”.
- Create custom excerpts that show where the hit was made, with the search terms highlighted.
- Highlight search terms in the documents when user clicks through search results.
- Search comments, tags, categories and custom fields.
- Adjust the weighting for titles, tags and comments.
- Log queries, show most popular queries and recent queries with no hits.
- Restrict searches to categories and tags using a hidden variable or plugin settings.
