[opencms-dev] How do I stock the first letter of a field in Solr ?

[Siegfried Ehret]

Hi,
I want to make a filter by first letter for my elements.
I can't use a solrQuery since they don't accept query for one letter.
Hence, I want to do this using a special field, where I will store the first letter from my element's title.

Thanks in advance
