Solr highlighter and custom queries?

[Daniel Shane <sh...@lexum.com>]

Hi all!

I'm trying to do some simple highlighting, but I cannot seem to figure out how to make it work.

I'm using my own QueryParser which generates custom made queries. I would like Solr to be able to highlight them.

I've tried many options in the highlighter but cannot get any snippets to show.

However, if I change the QueryParser to the default solr parser it works.

There is certainly a place in the config or in the query parser where I can specify how Solr can highlight my custom queries?

I checked a bit in the source code, and in WeightedSpanTermExtractor class, in the method extract(Query query, Map terms), there is a huge list of instanceof's that check which type of query we are attempting to match.

Is that the only place where the conversion between query <-> highlighting happens? If so, its looks pretty hard coded and would not work with any other queries than the ones included in Lucene.

I guess there must be a good reason for this, but is there any other way of making the highlighter work without having to hard code all the possible queries in a big if / instanceofs?

If we could somehow reuse the code contained in each query to find possible matches, it would avoid having to recode the same logic elsewhere.

But as I said, there must be a good reason for doing it the way its already coded.

Any ideas on how to work this out with the existing code base would be greatly appreciated :)

Debugging - DIH Delta Queries-

[Vladimir Sutskever <Vl...@jpmorgan.com>]

Hi All,

How can I see all of the queries sent to my DB during a Delta Import?

It seems like my documents are not being updated via delta import
When I use SOLR's DataIMport Handler Console - with delta-import selected I see

<lst name="entity:getall">
<lst name="document#1"/>
</lst>
−
<lst name="entity:getall">
<lst name="document#1"/>
</lst>
−
<lst name="entity:getall">
<lst name="document#1"/>
</lst>


But that’s not very helpful - I want to see the exact queries


Thank You
