Hi all,
I try using concurrently SynonymFilter and
FastVectorHighlighter,
then I got empty highlight response.
As investigation of the causes, I set all combination of
hl.useVectorHighlighter and expand attribute.
-------------------------------
<filter class="solr.SynonymFilterFactory
synonyms="syn.txt"
ignoreCase="true" expand="false"/>
-------------------------------
Result:
expand="true" in solrconfig.xml,and
hl.useFastVectorHighlighter=true
-> Returned highlight is empty as below.
-----------
<lst name="highlighting">
<lst name="404"/>
<lst name="401"/>
<lst name="89"/>
<lst name="155"/>
<lst name="411"/>
</lst>
-----------
expand="false" , and hl.useFastVectorHighlighter=true
expand="true" , and hl.useFastVectorHighlighter=false
expand="false" , and hl.useFastVectorHighlighter=false
-> On these cases,Highlighting has correct snippet.
Are SynonymFilter and FastVectorHighlighter not supported
using concurrently?
These component are not compatible?
In additional:
- target field type is defined as following
- target field is tokenized by CJKTokenizer.
- This problem occured only when I search japanese
keyword.
but not occured when English keyword.
(trouble was caused by n-gram tokenize?)
-----------
<fieldType name="text_cjk" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.CJKTokenizerFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.CJKTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignore
Case="true" expand="true"
tokenizerFactory="solr.CJKTokenizerFactory"/>
</analyzer>
</fieldType>
