That's called phrase query - selecting documents based on the order of the
terms. Just enclose the terms in quotes.

Thanks Jack!
Do you have any idea how can I select documents according to the appearance
order of the terms?

pf and ps merely control boosting of documents, not selection of documents.
mm controls selection of documents.
So, hopefully at least doc3 is returned before doc2.

Hi,
We have an index with 3 documents, each document contains a single field let’s
call it ‘text’ (except the id) as below:
· Doc1
o text:home garden sky sea wolf
· Doc2
o text:home wolf sea garden sky
· Doc3
o text:wolf sea home garden sky
When executing the query: home garden apple,
Using eDismax params:
· pf=text
· ps=1
· mm=2
We would like to get Doc1 and Doc3, in other words all the documents having
at least 2 terms in close proximity (only 1 term off).
The problem is that we get all 3 documents, it looks like the ‘ps’ parameter
doesn’t count.
Why Doc2 included in the results? We expected that Solr will emit it since
the ‘ps’ is larger than 1 => we have home wolf sea garden (ps=2?)
