All,
I'd like to add a new synthesized field that uses a phonetic analyzer
such as Beider-Morse. I'm using Solr 7.2.
When I request the current schema via the schema API, I get a list of
existing fields, dynamic fields, and analyzers, none of which appear
to be what I'm looking for.
Conceptually, I think I'd like to do something like this:
add-field: { name: phoneticname, type: phonetic, multiValued: true }
... but how do I define what type of data "phonetic" should be?
I can see the example XML definition in this document:
https://lucene.apache.org/solr/guide/7_2/filter-descriptions.html#Filter
Descriptions-Beider-MorseFilter
But I'm not sure how to add an analyzer to the schema using the schema
API: https://lucene.apache.org/solr/guide/7_2/schema-api.html
Under "Add a new field type", it says that new analyzers can be
defined, but I'm not entirely sure how to do that ... the API docs
refer to the field type definitions page[1] which just shows what XML
you'd have to put into your schema XML -- which you aren't supposed to
edit directly.
When looking at the JSON version of my schema, I can see for example thi
s:
"fieldTypes":[{
"name":"ancestor_path",
"class":"solr.TextField",
"indexAnalyzer":{
"tokenizer":{
"class":"solr.KeywordTokenizerFactory"}},
"queryAnalyzer":{
"tokenizer":{
"class":"solr.PathHierarchyTokenizerFactory",
"delimiter":"/"}}},
So should I create a new field type like this?
"add-field-type" : {
"name" : "phonetic",
"class" : "solr.TextField",
"analyzer" : {
"tokenizer": { "class" : "solr.StandardTokenizerFactory" },
"filters" : [{
"class": "solr.BeiderMorseFilterFactory",
"nameType": "GENERIC",
"ruleType": "APPROX",
"concat": "true",
"languageSet": "auto"
}]
}
}
Then, use copy-field as "usual":
"add-field":{
"name":"phonetic",
"type":"phonetic",
multiValued: true,
"stored":false },
"add-copy-field":{
"source":"first_name",
"dest":"phonetic" },
"add-copy-field":{
"source":"last_name",
"dest":"phonetic" },
This seems to work but I wanted to know if I was doing it the right way.
Thanks,
- -chris
