Relevanssi has a minimum word length setting that is set to three characters. Any one- or two-letter words are not indexed unless you change this setting from the Relevanssi advanced indexing settings. Sometimes it would be helpful to ignore short words but to index one- and two-digit numbers.
You can do that with a bit of help. Adjust the minimum word length to 1 or 2 depending on your needs, add this function to your site and rebuild the index:
add_filter( 'relevanssi_remove_punctuation', function( $str) {
return implode(
' ',
array_filter(
explode( ' ', $str ),
function( $word ) {
if ( relevanssi_strlen( $word ) < 3 ) {
return is_numeric( $word );
}
return true;
}
)
);
} );This function will let short numbers through while blocking short words.
I’m not sure this snippet is working. After adding it to my functions.php file, and rebuilding the index, searching for two-digit numbers still returns “No Results”
Default view (no search): https://tppr.me/5Ymd1D (notice the two and three-digit office numbers marked on the screenshot)
Three-digit number search: https://tppr.me/QxdmvB (returns results)
Two-digit number search: https://tppr.me/Cmlr9c
Is there a chance that the provided function (that should enable indexing < 3 character words if they are numerical) is not working?
Daniel, did you also adjust the minimum word length to 2 from the advanced indexing settings?
The function works for two-digit numbers, but in your case, it’s possible this function runs before the one that removes punctuation, so “2-46” is not a two-digit number when this function runs. Try changing the priority of this function to bigger than 10 (
add_filter( 'relevanssi_remove_punctuation', function( $str) {...}, 11 );).Hi Mikko, thank you for the prompt reply.
Changing the priority of the function solved the issue.
Thanks once again, appreciate the quick response!
