if use multi index box, how to pagination with sort by score correctly?
for example, i wanna query search with 60 index box and sort by score.
i don't know the num found from every index box which have different
content.
if promise 10 page with sort score correctly, i think solr 's start is 0,
Hi,
I am getting the following exception when I try run any query :
java.lang.NumberFormatException: empty String

The default search field is really handy. It helps simplify
the query, and thus simplify the application using solr.
My understand is that solr only allows one default search field.
It would be useful to allow multiple default fields, and maybe
also specify a global field boost in the schema

I've needed similar logged information recently and I looked at the code
and had a few questions:
Why does SolrCore.setResponseHeaderValues(...) set the QTime (and other
response header options) instead of having it as a function of
RequestHandlerBase? If things were tracked in the
: q=samsung+camera
:
: And if samsung is mandatory, the query will be like this: (or not:)

: q=+samsung+camera

: And the first + will be interpreted as mandatory flag?
No. bottom line, forget all about URLs and URL escape. step #1:
understand the Lucene query syntax...

Hi matej,
since I didn't see anyone answering your question yet, I'll have a go at
it, but I'm not one of the Solr developers, I've just used it so far and
am very happy with it. I use it for searching literary texts, storing
information from a SQL database in the Solr documents as metadata
Regarding the Lemma and PoS-tag requirement: you might handle this by
inserting each word as its own document, with lemma, pos, and word
fields, thereby allowing you lots of search flexibility. You could also
include ID fields for the item and (if necessary) part (chapter etc.)
and use these as

: recip(popularityRank, 1, 1000,
: 1000)^0.5recip(rord(creationDate),1,1000,1000)^
: 0.3
: /str
off the top of my head, i'd suggest you:
1) verify there is some whitespace between the boost of the
popularity recip function and the

Hi Chris
The /var/www/html/solr/data/ directory did exist. I tried opening up
permissions completely for testing but no luck (the tomcat user had
write permissions).
I decided to trash the whole installation and start again. I downloaded
last nights build and untarred it. Put the .war into

I'm not sure I understand the question.
When combining results from partitions, you can't use startAt. You
must always assemble the docs
thks for your detail answer.
but u ignore sorted by score
p1, p2,p1,p1,p3,p4,p1,p1
maybe their max score is lower than from p19,p20.
so it will not sorted by score correctly.
and if user click page 2 to see, how to show data?
p1 start from 10 or query other partitions?

2) eliminate the space inside the recip functions
This solved it :)
I would like to document this along with a little detail about function
queries may be if I get enough time, simple graphs that I created to help
people choose the right values for using in the function queries.
I dont see
for example, i wanna query lucene, it's numFound is 234300.
and results should sorted by score.
if u do, how to pagination and sort it's score?

Please check - http://wiki.apache.org/solr/FunctionQuery
and send me your comments (or improve the wiki )
Right now its more of a aggregation of all relevant information.
I hope people will be able to add notes like what values to use, pitfalls to
avoid, behaviour in special cases as
