Open Source Document Management

I installed the CE version, we loaded 92 files of various types, word, pdf, mp3 etc ... LogicalDoc has indexed everything, but the Fulltext search works only for words within the readable files and not by looking for words of the name of the file, but only if I write the full file name extension. It's normal?

You should understand that full-text search is quite different by standard query search like you do on a database. That is because every word is parsed by an indexer algorithm.
So in order to search for filename in the full-text search you should add special characters like '*' asterisk or include a word in double quote '"'

Note: FYI in the commercial editions of LD there is a parametric search that allows to query the archive like you do via sql https://docs.logicaldoc.com/en/search/parametric-search
