[Plugin: Relevanssi – A Better Search] Using posts_search filter in RelevanSSI (or equivalent)

  • Hi Mikko,
    Awesome plugin! I have run into a bit of a snag – you mention that RelevanSSI replaces the default WordPress Search, does it also override the posts_search filter? I wrote https://pastebin.com/XnvbfpfS which basically takes the search term, finds if it has ‘TL’ in the term and then returns (in addition) ‘TL-‘ as a search term pre/appended onto whatever else is attached to it). After enabling RelevanSSI, the filter does not work anymore. Is relevanssi_do_query() what I’m looking for here? Do you have a quick example of how I could plug into this area? Thanks!

    This is being used to search for post titles –> as most people type in TL123 instead of TL-123 (the filter I wrote attempts to fix that)

    I tried to use the “synonym” area, but I believe it’s looking for whole terms and not “parts of terms”. Is there any regex available in that area as well?

    Use the Relevanssi filter hook relevanssi_mofidy_wp_query to change search query ($wp_query->query_vars[‘s’]) before Relevanssi sees it.

    If you add the variant form to the search query, make sure you’re using OR operator.

    Hi Mikko,
    Thanks for the response. Here’s what I have so far: https://pastebin.com/baA6KxFb

    But after I have the “new_search” variable, I’m not sure how to plug it into wp_query and also change the operator to OR. Would you be able to help me hook that part up? I’d really appreciate it – will be buying the developer version once I know this part works as needed. Thanks!

    Hi Mikko,
    Emailed through regular support (with developer version license). Thanks.

    Once you have the search string with the added parts, just store it in $wp_query->query_vars['s'] and return the updated $wp_query. That’s all there is – you don’t have to worry about queries or MySQL code.

    So, if $wp_query->query_vars['s'] is “TL123”, you need to modify it to “TL123 TL-123” and then store that in $wp_query->query_vars['s']. Nothing else.

    The default operator is set on the Relevanssi settings page, look there.

    Very cool! Here’s the final result: https://pastebin.com/huke6FNe

    For everyone else (which I’ll be doing as well), just pass in that $replace_var via something more dynamic (like a plugin option) so you can change that from site to site.

    Thanks again Mikko!
