Excerpts still not working on partial matches?

[Sjors]

I was wondering if this problem is still around or if I'm doing
something wrong. In 2009 Pat wrote [0] that you can't get excerpts on
partial matches, that this was due to a "bug" in Sphinx itself and
that this might get fixed in the near future.

I'm using the latest version of Sphinx from SVN and thinking-sphinx
2.0.5. I can get excerpts on full word matches, but not on partial
word matches.

Cheers,

Sjors

Hi Sjors

This is now possible in Sphinx - and should be fine with Thinking Sphinx provided you're using wildcards in your query. For example:

ThinkingSphinx.search('pow*').first.last_name #=> "Power"
ThinkingSphinx.search('pow*').first.excerpts.last_name #=> "<span class=\"match\">Power</span>"

How are you using it where it's not working?

Hi Pat,

I wasn't using wildcards, because I want it to return partial matches
without the user typing "*" (especially with autocomplete). So I only
set:
:min_infix_len => 1

After adding
:enable_star => 1
all search results have excerpts, so that's good.

As a workaround, I can simply add "*" to all search queries in the
controller so the user doesn't have to type "*".

Thanks,

Sjors

You can also pass :star => true into the search query, and it'll automatically add prefix and suffix stars to each word in the search query.

You can change the excerpts highlight tags using something like this:

Model.search 'foo',
:excerpt_options => {:before_match => '<em>', :after_match => '</em>'}

Just make those empty strings if you don't want any highlighting of matches at all.

It it possible to highlight only matched part? For example return ThinkingSphinx.search('pow').first.excerpts.last_name #=> "<span class=\"match\">Pow</span>" 

So NOT to match a whole word.

I believe that Sphinx shows you what it matched after doing any stemming or fuzzy matching, not precisely the string you entered. From it's point of view, that's the "match". If you wanted to highlight the precise string entered, you may want to look at a JavaScript solution instead of using the Sphinx highlighter.

Hi Andrey

I have a feeling what you want is not possible, but I’m not sure. It’s a question that’s probably better to direct to the Sphinx team - Thinking Sphinx just uses the excerpts functionality of Sphinx itself.
