I'm having trouble searching keywords
For example, if you search for a Mercedes cla
The result will show you all models and anything that says Mercedes and Cla.


How can the search be made accurate and come up with the words that the visitor is searching for?
This means that in our example, the search should return ads for Mercedes CLA only
Thank you all

Update database index.
Check different search engine options in Settings > General.

Search results do not appear in all languages
For example, if a person searches for BMW, the results will not appear for him unless he chooses the English language, but if he chooses another language, the results will not appear as if there is no item with that title.

And I’ve been talking about this for a long time, apparently the developers don’t understand how deep the problem is with a multilingual site.  Likewise, if a user submits an ad in English and then switches the site to German, he will no longer find his text, it does not exist in German.  What's the point of having a multilingual website if it doesn't work!!!?

@Vlad7
Very simple - words means something different in different languages.

Without fixing the language issue the script is useless
Unfortunately, this is something we regret very much
Most sites of this type must include multiple languages, such as:
French - English - Spanish - Italian
All the languages I mentioned have the same names for cars, for example
BMW is written with the same form, meaning and letters in all languages, as well as for all types of cars
