Search function is working (was not customized apart from providing the search account) and returns results as expected when I search for words or substrings of document titles like "template" or "C03".
However, when I search for e.g. "C03-2012.09.11-SG-01" (which is a document number and part of a document's title like "C03-2012.09.11-SG-01_MyDocument.doc") I get wired results. E.g. for the search term "C03-2012.09.11-SG-01" (there is one correponding document whose title starts with this string) it finds a document that starts with "C03-2011.09.08-SG-02" and displays it with 09 in bold letters. When I search for exactly this search result by entering "C03-2011.09.08-SG-02", I get not results at all.
Maybe I missed important step(s) configuring the search, please advise. I also seem not to really understand how a search term like C03-2011.09.08-SG-02 is interpreted by the search. As the results indicate, the search does not look for something that contains the search term as a substring.
