Match phrase and minimum_should_match combination

[Zdeněk Šebl]

Hi,
I try to use *ngram* based solution as "shotgun approach" to get results 
which are not covered by more precise analyzers.

Article describing this approach is for example here 


*Match* query, it is working as expected including parameter 
minimum_should_match (this parameter is very important to be able to 
exclude matches of only one ngram from queried word).

*1.* Below is explanation of *match* query searching word *"first"* without

filtered(Text:fir Text:irs Text:rst)->cache(_type:item)

and with "minimum_should_match": "80%"

filtered((Text:fir Text:irs Text:rst)*~2*)->cache(_type:item)

2. But if I try to use the same with *match_phrase* query and phrase *"first 
second"* I'll get the same result with or without minimum_should_match 
parameter

filtered(Text:"(fir irs rst) (sec eco con ond)")->cache(_type:item)

I 'am expecting (for minimum_should_match) something like

filtered(Text:"(fir irs rst)*~2* (sec eco con ond)*~3*")->cache(_type:item)

In attached file, there is complete Marvel Sense code with example 
described above.

*Does anybody know if it is a bug or if it known limitation of used 
technology?*
Or maybe there is another way how to achieve better phrase query results in 
combination with ngram analyzer.

Thanks,
Zdenek
