> URL: https://issues.apache.org/jira/browse/LUCENE-6493
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Affects Versions: 5.x
> Reporter: Jeroen Steggink
> Priority: Minor
> Attachments: LUCENE-6493.patch

>
> When performing MoreLikeThis queries we have a lot of parameters at hand in
> order to finetune the results. However, one thing I personally missed, being
> able to set a minimum of matching terms.
> The advantage of this parameter is that Lucene will retrieve only the
> documents which have at least the given number of matching terms and you
> won't get any results of just one or two keyword matches when you are looking
> for documents that have more than a few matching interesting keywords.
> An example:
> doc1: lucene
> doc2: lucene release
> doc3: apache
> doc4: apache lucene
> doc5: apache lucene release
> Let's say the query is "apache lucene release" and you set the minimum number
> of matching interesting terms to 2.
> MoreLikeThis will return:
> doc2, doc4 and doc5
> Would you set it to 3, it would return just doc5.
