Premium 1.10

The beta testers had no complaints, so here goes: Relevanssi Premium 1.10 and a ton of updates.

• Made some changes to how user profiles and taxonomy terms are handled. As a result, there should be less warning notices. For user profiles, you can now find the user id in $post->user_id and for taxonomies, the term id is $post->term_id.
• Deleting users and taxonomy terms caused problems. Fixed that.
• Fixed a notice about undefined variable on plugin update pages.
• Small bug fixes on search to remove warning notices.
• New filter: relevanssi_index_custom_fields can be used to modify the list of custom fields to index.
• Deleting menus caused a warning. That is now fixed.
• Relevanssi has an option to disable IP logging (which is actually illegal in some countries). Thanks to Stefan Eufinger.
• Searching in subcategories worked sometimes, but not always. Thanks to Faebu.
• The “Limit searches” option didn’t work too well in the case of strong weightings, as it didn’t take note of any weights. Now it works better.
• Added a note about disabling custom excerpts when they are not needed – they can slow down the search quite a bit.
• New filter: relevanssi_options_capability can be used to modify the capability required to see the options page (default is manage_options).
• External search highlighting from Google doesn’t work anymore, because Google doesn’t pass the search term in referrer fields. Fixed the highlighting for Yahoo searches.
• Fixed the way IDF is calculated to account some extreme cases with small databases.
• Fixed filter: relevanssi_pre_excerpt_content wasn’t working properly.
• Relevanssi now supports tax_query, for most part. You can query multiple taxonomies, use relation AND and OR, use operators AND, IN and NOT IN and choose include_children (which defaults to true). Old taxonomy and term still work, but I recommend using tax_query for the level of control it offers.
• Relevanssi now works better with category restrictions. The extra cats query variable is no longer necessary, Relevanssi can now read multiple categories from cat. You can also use category__and, category__in and category__not_in.
• Same goes with tags: tags is now longer necessary. Relevanssi has full support for tag, tag_id, tag__and, tag__in, tag__not_in, tag_slug__and, tag_slug__in and tag_slug__not_in. For tag, both term1+term2 and term1,term2 is supported.
• Relevanssi now supports author_name and negative values for author.
• Relevanssi now supports offset query variable.
• Relevanssi now supports meta_query. You can use all comparisons (also EXISTS and NOT EXISTS, even if you don’t have WP 3.5). You can also use the older meta_key and meta_value query variables, including all the comparisons. I have not tested all possible meta_query constructions, so bug reports of things that don’t work as expected are welcome.
• New index on the database makes some database operations faster.
• New filter: relevanssi_user_add_data lets you add extra data to user profiles before indexing them.
• Removed a bug that prevents one-character words from being indexed in titles, despite the minimum word length setting.
• Removed a warning when searching for nothing.
• Fixes a warning about $wpdb->prepare() caused by a change in WordPress 3.5.

The most significant changes are in the way the taxonomy and meta queries work. Now you can take almost any WP_Query parameter and use it to modify the Relevanssi results. Building complex taxonomy queries is now much easier than before.

I’ll update the manual with the new filters shortly.
