Hello, I'm writing an xwiki application and I start fighting with solr search. On http://extensions.xwiki.org/xwiki/bin/view/Extension/Solr+Search+Query+API#… I read "The list of typed (non-string) dynamic fields that will be expanded in the search query. The names of these fields are suffixed with the name of their data type (e.g. *_int is a dynamic integer field)." Unfortunaly in my application I use same prefixe in my properties name (_) to add some dynamic bootstrap tab (and another things)! An example: CodeH_Deb_P1 or P1_EaAutrDO_Cond_Invisi I suppose _ is hardecoded in xwiki, then I must replace all my _ character in my properties name and Sheets code but could you suggest a character I can use without problem? This one ~ perhaps? By the way: I didn't manage to make this example work with this code on xwiki 6.4+Expense Report Application: http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingCustomSolrSearchFo… Thxs.
