> Patch adds a configuration variable for setting slop values on phrase
> queries. The default slop value, which currently can't be changed through
> configuration, is Integer.MAX_VALUE. It produces something like this, which
> doesn't seem right to me. If you are searching for a phrase you usually want
> it within a certain distance:
> 2.9141337E-4 = weight(content:"my phrase"~2147483647 in 1029), product of:
> * 0.07163286 = queryWeight(content:"my phrase"~2147483647), product of:
> o 9.657982 = idf(content: my=13470 phrase=534)
> o 0.0074169594 = queryNorm
> This patch adds the query.phrase.slop configuration value to the
> nutch-default.xml file. It has a default setting of 5.
