First you need to know about the Lucene's ranking concept.
Lucene's basic ranking is BM25 and it depends on your index status.

There can be many reasons.
One of thing that I can guess is your index has a lot of 'rozi' term so it
is getting
i would suggest trying (indexing and searching) without === ' === s and
see You can find it first.
Thanks

I am currently matching botanic names (with possible mis-spellings)
against an indexed referenced list with Lucene. After quick progress in
the beginning, I am struggeling with the proper query design to achieve
a ranking result I want.
Here is an example:
Search term: Acer campestre 'Rozi'
i see, i am using an older version 6.6 and we should switch to Your 8.1
version of at least 7.X.
Tomoko i think i understood You meant MAIN NASHUA for the string :)
Again i really appreciate all answers.
How do we disable or enable stemming while indexing? :) another question.

1. Indexed this text: "MAIN DUNSTABLE NASHUA HILLSBOROUGH NEW
HAMPSHIRE UNITED STATES"
As far as I can say, this query

Shot in the dark: stemming. Whenever I see a problem with something ending in
“s” (or “er” or “ing” or….) my first suspect is that stemming is turned on. In
that case the token in the index that’s actually searched on is somewhat

That is strange indeed.
Something is wrong when i use mains but maink, mainl, mainr,mainq, maint

Case #3 had +contentDFLT:mains~2 but not +contentDFLT:"mains~2".
i am using fuzzy query with ~ from Query.builder and
10 matches
