Question about Qsol parser and phrase searches
I have a document that contains the phrase "recent stent placement". Here is
the result of some queries using the Qsol parser:
"recent stent placement" => YES
"recent placement" => YES
"recent placement":0 => NO
"recent placement":1 => YES
where YES/NO indicates whether the document was returned. The "recent
placement" query result surprised me, as I had expected it not to return the
document. From the other queries, it looks like phrase searches have a
default slop of one. Is that correct? If so, is there a way to default to no
slop, preferrably without changing all of our queries?
Thanks for any pointers.
Jeff

The default slop is one and it really should be 0. Sorry about the slip
up Jeff and thanks for catching it. I'll make an adjustment, and a
method to allow changing the default anyway, and then point you to an
updated jar.
