[KinoSearch] question on querying by url

[Kevin Kamel]

Hi Fil,

   I'm pretty sure that the search syntax that you are trying isn't
supported by Kinosearch. Prefixing search terms with "url:" is a syntax that
is supported by the Plucene and Lucene parsers, but I have not seen any
documentation in the KinoSearch CPAN docs to indicate that this is
supported.

   I think we are actually doing something similar. I have several fields
that I am indexing separately, and I want to be able to search through all
of them, potentially in combination with eachother (this and that,
specifically), like a standard search engine type of search.

   In order to accomplish this I had to use a combination of terms to store
my query strings, instantiate TermQueries to create query objects using the
terms, and finally create combination queries using the BooleanQuery object.
I suggest you look at this page for pretty specific instructions on how to
proceed:
