I am trying to come up with a way to sort (or score, and sort based on
the score) of a multivalued field. I was looking at FunctionQueries and
saw fieldvalue, but as that only works on single valued fields that
doesn't help me.
The field is as follows:
<fieldType name="keyword" class="solr.TextField"
sortMissingLast="true" omitNorms="true">
<analyzer>
<!-- KeywordTokenizer does no actual tokenizing, so the entire
input string is preserved as a single token
-->
<tokenizer class="solr.KeywordTokenizerFactory"/>
<!-- The LowerCase TokenFilter does what you expect, which can
be
when you want your sorting to be case insensitive
-->
<filter class="solr.LowerCaseFilterFactory" />
<!-- The TrimFilter removes any leading or trailing whitespace
-->
<filter class="solr.TrimFilterFactory" />
</analyzer>
</fieldType>
<field name="myfield" type="keyword" index="true" stored="true"
multiValued="true" />
The actual data that gets put in this field is a string consisting of a
number, a space, and a 1 or a 2. For example:
"818 2"
"818 1"
"950 1"
"1022 2"
I want to be able to give my search results given a boost if a
particular document contains "818 2" and a smaller boost if the document
contains "818 1" but not "818 2".
The end result would be documents sorted as follows:
1) Documents with "818 2"
2) Documents with "818 1" but not "818 2"
3) Documents that contain neither "818 2" nor "818 1"
Is this possible with solr? How would I go about doing this?
