[TYPO3-Solr] No Results with search queries including single number

[b.riezler at pixel-ink.de]

Hi all,

i have some problems with search queries wich are including numbers, like "Formel 3" or "Formula 3" (search query is without quotation marks).
We have created a Index where the search query is included in multiple fields such as content, teaser and others.
These Fields are all included in the search fields but the search doesn't give any hit if we search for a string with a number.

If i send the query via the Solr Admin it gives me all the files and documents with the search words in it.

How can we fix this. When we are searching for a query like "Formel V" we also get results, but when we replace it with a number nothing is found.

Best
Benjamin
