Input normalisation for property restricted search using the keyword search syntax RRS feed

  • Question

  • Hi guys,

    It seems to be the case that if property restriction is used in a keyword search syntax, the input is not normalised. i.e.

    title:"Öcalan" will not return the same as title:"Ocalan"

    Is there a way around this?

  • The problem was stemming. For any given field you can only turn on either sub-string support or stemming. Stemming doesn't just convert words to their stem form, it also normalises them into a standard set of characters.

  • Hi Emir, that is indeed strange.

    Have you figured this one out?

    If not: could you please check the querylogs (FAST_installation_path\var\log\querylogs) in FS4SP to see that the query is indeed the same?

    This can help us track down where the error is originating.
