Ok, I know shingling will join with "_".
But that is the behaviour we want, imagine we have this fields (contained in
species file):
abarema idiopoda
abutilon bakerianum
Those become in:
abarema
idiopoda
abutilon
bakerianum
abarema_idiopoda
abutilon_bakerianum
But now in my genus file maybe is only the word abarema, so, we end up with
a field with only that word.
So, the requirements here, are to be able to find all species in species
files (step one) and then make a facet with species in file genus, step two.
It seems reasonable to just chain the fields, I just forgot solr didn't
change the field, as Shawn points (thanks for it).
So what we came here is to make 2 fields the first with species.
<fieldType name="species_type" class="solr.TextField"
positionIncrementGap="0">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping/mapping-ISOLatin1Accent.txt"/>
<charFilter class="solr.PatternReplaceCharFilterFactory"
pattern="[0-9]+|(\-)(\s*)" replacement=""/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ShingleFilterFactory" maxShingleSize="3"
outputUnigrams="true"/>
<filter class="solr.KeepWordFilterFactory" words="species.txt"
ignoreCase="true"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.ShingleFilterFactory" maxShingleSize="3"
outputUnigrams="false"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
And the second one (genus), which contains genus that has to be for facet
purposes, like this:
<fieldType name="genus_type" class="solr.TextField"
positionIncrementGap="0">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping/mapping-ISOLatin1Accent.txt"/>
<charFilter class="solr.PatternReplaceCharFilterFactory"
pattern="[0-9]+|(\-)(\s*)" replacement=""/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ShingleFilterFactory" maxShingleSize="3"
outputUnigrams="true"/>
<filter class="solr.KeepWordFilterFactory" words="species.txt"
ignoreCase="true"/>
<filter class="solr.KeepWordFilterFactory" words="genus.txt"
ignoreCase="true"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Nevertheless, there is no second processing for keep word filter as (I)
expect. Am I missing something?
