Search not indexing correct languages in QtranslateX

Is the problem in indexing or in searching? I’d check that first. Does the word “chimie” appear in the wp_relevanssi database for the correct post?

In any case, I don’t know how qTranslate-X works in the first place, so I’m not sure how compatible it is with Relevanssi. Does it create multiple copies of the post?

Hi Mikko,

I’ve checked and the term chimie doesn’t appear in wp_relevanssi for the post.

qTranslateX keeps all languages in the same post. For example, in wp_posts the post title for this post in English/French is:
[:en]Chemistry of Biomolecules[:fr]Chimie des biomolécules[:]

So when I search in wp_relevanssi for the right post ID with title = 1, the only words indexed are Chemistry and Biomolecules.

Do you have any idea why? The tags [:en] and [:fr] doesn’t seem to be a problem because the words in english are correctly indexed.

In that case I think the problem is that qTranslateX filters the title somehow before Relevanssi sees it, and Relevanssi only sees the English title. How to fix that, I don’t know.

Yes, qTranslateX filters the title so in Relevanssi, indexing.php line 319:

$titles = relevanssi_tokenize(apply_filters('the_title', $filtered_title, $post->ID), apply_filters('relevanssi_remove_stopwords_in_titles', true));

When using apply_filters(the_title) only the default language is being indexed.

Is it possible to not use apply_filters(the_title) because all terms are present in $post->post_title ?

Thanks,

That filter must be applied there, because other plugins depend on it.

However, Relevanssi first runs the title through the relevanssi_post_title_before_tokenize filter. You could add a filter function there that strips out the qTranslateX codes, so when the title then goes through the_title, they’re not there anymore.

Ok I did what you suggested.

Is there any way to re-index specific posts to see if it is working?

Just save the post.
