Hoss Man commented on SOLR-3028:
--------------------------------
#1) maybe i'm missundertanding SOLR-2866 ... it talks about synonyms, but the
crux of it is really indexing multiple variants of a stemmed word with
informatino about wether it is a stem or not, and then being able to query on
both -- your requrest seems to heavily overlap with that -- in Victor's case he
may be using a dictionary based stemmer, and in your case you may want a
hueristic stemmer, but the underlying plumbing should probably all be the same.
#2) sorry, yeah i missed your label and only looked at the example. quorom
search is definitely possible using the dismax parse with the mm param, but
there is no explicit syntax for it in any parser i know of at the moment.
#3) the curly braces in that example were just me being explicit about which
parser was in use via local params -- that's not the query syntax. you could
just as easily do...
{code}
defType=surround&q=(this W that) AND (other W next)
{code}
In generallymy suggestion for moving forward would be to break these individual
requests out into 3 distinct issues since they are largely unrelated (or only
open two issues and ask about #1 in SOLR-2866 .. make an offshoot issue as
needed)
individual issues with more direct issue summaries are easier to track and more
likely to encourage patches from people who see the summaries and realize it's
something they are interested in.

> Key: SOLR-3028
> URL: https://issues.apache.org/jira/browse/SOLR-3028
> Project: Solr
> Issue Type: Improvement
> Components: search
> Affects Versions: 4.0
> Reporter: Mike
> Labels: operator, queryparser
> Original Estimate: 6h
> Remaining Estimate: 6h
>
> I'm migrating my system from Sphinx Search, and there are a couple of
> operators that are not available to Solr, which are available in Sphinx.
> I would love to see the following added to the Dismax parser:
> 1. Exact match. This might be tricky to get right, since it requires work on
> the index side as well[1], but in Sphinx, you can do a query such as [
> =running walking ], and running will have stemming off, while walking will
> have it on.
> 2. Term quorum. In Sphinx and some commercial search engines (like Recommind,
> Westlaw and Lexis), you can do a search such as [ (cat dog goat)/15 ], and
> find the three words within 15 terms of each other. I think this is possible
> in the backend via the span query, but there's no front end option for it, so
> it's quite hard to reveal to users.
> 3. Word order. Being able to say, "this term before that one, and this other
> term before the next" is something else in Sphinx that span queries support,
> but is missing in the query parser. Would be great to get this in too.
> These seem like the three biggest missing operators in Solr to me. I would
> love to help move these forward if there is any way I can help.
> [1] At least, *I* think it does. There's some discussion of one way of doing
> exact match like support in SOLR-2866.
