Problem about range search
Hi,
I ran into a problem when trying range facet search. I had a schema define like this:
<fields>
<field name="title" type="string" indexed="true" stored="true"/>
<field name="author" type="string" indexed="true" stored="true" />
<field name="text" type="text" indexed="true" stored="true" />
<field name="path" type="string" indexed="true" stored="true" />
<field name="size" type="long" indexed="true" stored="true" />
<field name="lastmodified" type="date" indexed="true" stored="true" />
</fields>
I try to set up a range search on "size" field which stands for the size of a file. So I have the following requestHandler config in solrconfig.xml:
<str name="facet.range.other">after</str>
<str name="facet.range">size</str>
<int name="f.size.facet.range.start">0</int>
<int name="f.size.facet.range.end">15728640</int><!-- around 15M -->
<int name="f.size.facet.range.gap">3145728</int><!-- around 3M -->
But an error says: Unable to range facet on field:size{type=long,properties=indexed,stored,omitNorms,omitTermFreqAndPositions}
It doesn't show any clue, and I also tried <long> tag, but got the same error.
Could you please help to suggest?
Thanks in advance!

: 2. &fq=path:"E:\my_project\ecmkit\test" (return 0 result)
the problem in the first example is that evne though you have URL encoded the query string, you haven't done anything to escape the metacharaters that are special to the query parser.
In your second example, you've put quotes arround the value, which helps with some things -- but even in quotes you have to backslash escape the backslash itself...
fq=path:"E:\\my_project\\ecmkit\\test"
a far easier way to do what you are trying to do would be to use either the FieldQParserPlutin or the TermQParserPlugin...
fq={!field f=path}E:\my_project\ecmkit\test fq={!term f=path}E:\my_project\ecmkit\test
...no special escaping or quoting required

fq doesn't return any results
Posted by ZHANG Liang F <Li...@alcatel-sbell.com.cn>.
Hi,
I had field defined to store the location of a file:
<field name="path" type="string" indexed="true" stored="true" />
And the return value is something like:
<result name="response" numFound="25" start="0">
<doc>
<str name="path">E:\my_project\ecmkit\test</str>
...
But when I try to filter the result by using fq, None of the following return any results:
1. &fq=path%3AE%3A%5Cmy_project%5Cecmkit%5Cinfotouch (org.apache.lucene.queryParser.ParseException: Cannot parse 'path:E:\my_project\ecmkit\infotouch': Encountered " ":" ": "" )
2. &fq=path:"E:\my_project\ecmkit\test" (return 0 result)
Please help to suggest.
Thanks in advance.

Hi,
I just found the root cause. The definition for the 'long' type is not right. the previous definition was:
<fieldType name="long" class="solr.LongField" omitNorms="true"/>
which doesn't support range query! now I changed to : <fieldType name="long" class="solr.TrieLongField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>, and it's done!
Thanks a lot!

Hmmm, works fine for me using the "popularity" field in the default schema.
What version of Solr are you using? What is your complete handler definition?
