Hello, I hope someone can help me with this. I have a website which is
built on top of Solr and the home page is composed of 4 sections one
for each type of content on the site.

At the moment to populate this page, I am using 4 separate queries of the form:
?q=ContentType:News&sort=DatePublished+desc&start=0&rows=5
?q=ContentType:News&sort=Analysis+desc&start=0&rows=5
etc.
etc.

Can anyone think of a way I could reduce this to one query which
brings back the top 5 pieces of content for each content type by date?

Thanks in advance
Rupert

Your example though doesn't show different ContentType, it shows a different
sort order. That would be difficult to achieve in one call. Sounds like your
best bet is asynchronous (multi-threaded) calls if your architecture will
allow for it.

Sorry, my mistake, the example should have been as follows:

?q=ContentType:News&sort=DatePublished+desc&start=0&rows=5
?q=ContentType:Analysis&sort=DatePublished+desc&start=0&rows=5

I can't see a way of retrieving five results from one type and five from
another in a single query. The only way I can think about that would have a
similar behaviour would be:

?q=ContentType:(News+OR+Analysis)&sort=DatePublished+desc&start=0&rows=10

This way you'll have the first 10 results being News or Analysis, though it
could be 7 News and 3 Analysis or even 10 and 0...

If you need Solr to return 5 results from each type, I think the only way to
improve the search speed would be, instead of using just one query, making
two parallel queries.
