Hi Jack,
Here's q test query we've been using:
select?q=+engineer+boots&defType=edismax&fl=prodname&qf=prodnameplurals&pf2=prodnameplurals^2.0
This still produces a result set where the first 'engineer boot' is way down
the list and subsequent ones are interspersed with other boots. They're all in
there, just not at the top. Below is the debug on the first item that is an
engineer boot.
<str name="ITEM_3333">
0.23492618 = (MATCH) sum of:
0.23492618 = (MATCH) product of:
0.46985236 = (MATCH) sum of:
0.46985236 = (MATCH) weight(prodnameplurals:boot in 48270)
[DefaultSimilarity], result of:
0.46985236 = score(doc=48270,freq=1.0 = termFreq=1.0
), product of:
0.22236869 = queryWeight, product of:
4.8295836 = idf(docFreq=1867, maxDocs=86009)
0.046043035 = queryNorm
2.112943 = fieldWeight in 48270, product of:
1.0 = tf(freq=1.0), with freq of:
1.0 = termFreq=1.0
4.8295836 = idf(docFreq=1867, maxDocs=86009)
0.4375 = fieldNorm(doc=48270)
0.5 = coord(1/2)
</str>
Regards,
DQ

Show us your qf and pf params. Do you have PF2 set? That's the key for getting
the phrase "engineer boots" boosted higher than just boots. You may also simply
have to give a higher PF2 boost since "boots" probably has a much higher term
frequency than "engineer" or even the natural Lucene score for "engineer boot".
Also check the &debugQuery=true "explain" scoring to see how engineer, boot,
and "engineer boot" are being scored - you may have to add some specific query
phrases to force "engineer boot" into the top results to comparing the scoring.

Hi all,
We have an index of boots which contains harness boots, engineer boots , ankle
boots, etc. An edismax search on the index for 'harness boots' brings back
2,175 boots with 'harness' results at the top. 'Searching 'engineer boots'
brings back everything but 'engineer boots', same for 'ankle boots' - in fact,
same result set of 1,873 mostly boots but a few other products mixed in.
We're on SOLR 4.0 and the field we're querying is stemmed (snowball),
lowercased on WhiteSpaceTokenizer. Any ideas?
Regards,
David Q
