Hi,-
i will check explainOther parameter and see how it is used.
i am not sure the problem lies with countryDFLT since other search cases
with other consonants work fine but
i will check Your suggestions, thanks.
Btw, why is the rest of the query not showing up in the explain plan?
Best regards

BTW, if you have the ID of the doc you _think_ should be returned
you can see why it wasn’t by using the explainOther parameter.

Hi Baris,
Explanation's output is hierarchical, and the leading "0.0" values you
are seeing are the individual contributions of each boolean clause or
any other nested query.
Going from bottom to top:
Term query on countryDFLT = 'states', but no term matched this value
--> score is 0.0 for the term query "countryDFLT:states"
Term query is wrapped into a 'must' clause, but the term query scored
0.0 --> score is 0.0 for the 'must' boolean clause
"+countryDFLT:states"
Term query on countryDFLT = 'united', but no term matched this value
--> score is 0.0 for the term query "countryDFLT:united"
Term query is wrapped into a 'must' clause, but the term query scored
0.0 --> score is 0.0 for the 'must' boolean clause
"+countryDFLT:united"
(The two 'should' clauses with boosts have been optimized out; if a
single 'must' clause is present, they do not need to match at all,
unless you have minShouldMatch set on the boolean query)
Boolean query with two 'must' clauses did not match --> score is 0.0
for the boolean query "+countryDFLT:states +countryDFLT:united
(countryDFLT:uniten)^0.42000002 (countryDFLT:statesir)^0.56"
...and so on.
So Atri is correct, the index you are running this query on does not
seem to have a document where either 'united' or 'states' has been
indexed for field 'countryDFLT' (let alone both). Do the individual
building blocks, eg. "countryDFLT:united" return any results?

Hi,-
Any ideas on what might be happening?
maybe i am missing, is there an api to look into each contribution of
score into total scrore from the booleanquery?
Best regards

All must queries (and the rest of course) work ok when i search MAINK, MAINL,
MAINQ,..., MAINT etc.. for street name
with all consonants except S is used and all other fields are the same for all
queries (NASUA, HILLSBOROUGH, NEW HAMPSHIRE, UNITED STATES)
ie., working means: the top result is correct with MAIN.
But, with street name MAINS, and MAINO (with wovels) i cant get MAIN as top
result.
I have two theories:
either my query plan is too complex to handle MAINS (as there are some other
MAINS street in the index in other cities and states)
so maybe i need to run each component of booleanquery separately and then
manually post process them.
or my query plan is still not good enough to catch MAIN when i search with
street MAINS, city NASUA, municipality HILLSBOROUGH, state NEW HAMPSHIRE,
cuntry UNITED STATES
where the first two are fuzzy as they are have errors in them and the rest is
phrase query as they are correct
that is why i want to see each score from each of the component of the
booleanquery.
so far i checked Lucene but could not find a way to see each contributing score
to the total score for each result hit document.

It seems evident that multiple of your Must clauses are not matching any
document, hence no results are being returned?

Sure, here is the query plan: (i cant run explain plan as it does not
give me anything)
[+streetDFLT:maink~2 (streetDFLT:"maine")^0.35, +cityDFLT:nasua~2
(cityDFLT:"nasuh")^0.35, ++regionDFLT:"new-hampshire"
(regionDFLT:"new-hammpshire")^0.98, ++countryDFLT:"united"
(countryDFLT:"uniten")^0.42000002 +countryDFLT:"states"
(countryDFLT:"statesir")^0.56]
explain plan gives:
Explanation expl = is.explain(booleanQuery.build(), 10);
System.out.println(expl);
This prints:
0.0 = Failure to meet condition(s) of required/prohibited clause(s)
0.0 = no match on required clause (+regionDFLT:new-hampshire
(regionDFLT:new-hammpshire)^0.98)
0.0 = Failure to meet condition(s) of required/prohibited clause(s)
0.0 = no match on required clause (regionDFLT:new-hampshire)
0.0 = no matching term
0.0 = no match on required clause (+countryDFLT:united
(countryDFLT:uniten)^0.42000002 +countryDFLT:states
(countryDFLT:statesir)^0.56)
0.0 = Failure to meet condition(s) of required/prohibited clause(s)
0.0 = no match on required clause (countryDFLT:united)
0.0 = no matching term
0.0 = no match on required clause (countryDFLT:states)
0.0 = no matching term

It depends a lot on the actual clauses (whether they are SHOULD, MUST,
MUST_NOT), each query’s type (phrase, term etc).
Could you post your query and the explain plan of IndexSearcher post the
rewrite?
