Scoring in Lucene 6.6.0, 7.7.2, 8.1

Post #1 of 5 (545 views)

Hi,-

i really want to know why the scoring works this way: search String is
either MAINO or MAINS: MAIN appears as the 276th entry in the results.

NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 0 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 1 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 2 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 3 th result
NEW HAMPSHIRE in results: street="PENNICHUCK" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 4 th result
NEW HAMPSHIRE in results: street="HARTFORD" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 5 th result

NEW HAMPSHIRE in results: street="MARBLEHEAD" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 6 th result
NEW HAMPSHIRE in results: street="SPRUCEWOOD" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 7 th result
NEW HAMPSHIRE in results: street="FRENCH" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 8 th result
NEW HAMPSHIRE in results: street="KIM" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 9 th result
NEW HAMPSHIRE in results: street="HOBART" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 10 th result

when the booleanquery with fuzzy and phrasequeries are like in this
query plan:

[+streetDFLT:maino~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]

Why would Pennichuck come first before Main for Lucene 7.7.2 when MAINO
or MAINS is searched? (lets ignore entries without street)

Similarly with MAINS search on Lucene 6.6.0:

NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 1 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 2 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 3 th result
NEW HAMPSHIRE in results: city="NASHUA" municipality="HILLSBOROUGH"
region="NEW HAMPSHIRE" country="UNITED STATES" in the 4 th result
NEW HAMPSHIRE in results: street="MOUNTAIN VIEW" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 5 th result

NEW HAMPSHIRE in results: street="ELYSTAN" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 6 th result

NEW HAMPSHIRE in results: street="DOGGETT" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 7 th result

NEW HAMPSHIRE in results: street="WILLIAMS" city="NASHUA"
municipality="HILLSBOROUGH" region="NEW HAMPSHIRE" country="UNITED
STATES" in the 8 th result

why would Mountain View be given the top priority? (lets ignore entries
without street) with this query plan similar again.

All other consonant letters except S are fine.

Best regards

You can use IndexSearcher#explain to see how scores are computed.

This should be very straight forward usage but i am not getting any
usefeul info from explain:

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

for a query plan:
search Query:
[+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]

Let me ask the next question in another thread,

and it is:

how to find out each score contribution from a booleanquery.

Best regards
