Hi Erick,
thank you very much for your help. What's confusing me is that another
of my fields does not have any analyzers defined at all, and it's
working fine without problems. So, it must be possible to define field
type without specifying any analyzers. I don't understand why it
shouldn't be possible any more if either the index or the query analyzer
is specified and the other not. Maybe it would be clearer if Solr would
raise an exception in this case instead of using some analyzer that was
specified for the opposite type.
Anyway; I took your advice and used the KeywordTokenizerFactory instead.
Great! Now it does excactly what I want. Thanks again!
But may I ask another question? As with the categories, I have some
fields that are only used for faceting, so they're only queried by facet
results. No modification is needed, no lowercase, nothing. So the
KeywordTokenizerFactory is perfect for them.
Alas, when the value contains spaces, I'm still getting too many
results. I have a field defined like this:
<fieldType name="text_unchanged" class="solr.StrField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
</analyzer>
</fieldType>
(Using solr.TextField didn't change anything)
When quering for:
....&fq=label:Aces+of+London
I get the result:
.... "facet_fields":{
"label":[
"Aces of London",31,
"Feud London",2,
"Fly London",2],
....},
I get the same result when taking "Feud London" as the facet value.
When inspecting the index with the schema browser, I can see that all
labels are tokenized correctly in complete, i.e. there's no token
"London", but a token "Aces of London". So the KeywordTokenizer seems to
work as expected, at least for indexing. It's only that the facet query
is not narrow enough.
Even the superb Solr book didn't help me here. Do you - or any other -
has/have a clue what I'm doing wrong here?
Greetings,
Michael
