no search_api_solr results when search term ends with number I have search_api_solr with views (I use as external Solr server https://hostedapachesolr.com. )

There is this strange issue:

1/ When I search for 951, there are correct results

2/ When I search for V951L, correct results

3/ BUT ... when I search for V951: there are NO results at all ...

This weird behavior stays the same, even when I alter the "views" settings or the search_api_solr settings.
It's like the system is confused that the search term begins with a letter and ends on numbers.

Does anybody knows how to fix this ?

Best regards
I would try this.

Go into The solr server configuration - assuming it's named 'solr'
/admin/config/search/search-api/server/solr/edit

In Advanced, see if "Targeted content domain" is set to scientific. And see the description next to it to see why I'm thinking this might be your issue.

Save. You'll probably need to re-export your config zips and definitely need to clear and re-index.
