Hi Teko,
sure - I use Lucene though elasticsearch, but I suppose that doesnt make a
difference in this situation. I needed something like what you were trying
to accomplish - basically to search any substring... wildcarded queries
worked but were kind of slow.
This is my analyzer that works for me perfectly:
"settings" : {
"analysis" : {
"analyzer" : {
"default" : {
"type" : "custom",
"filter" : ["icu_folding"],
"tokenizer" : "nGram"
}
},
"tokenizer": {
"nGram" : {
"type" : "nGram",
"min_gram" : 2,
"max_gram" : 20,
"token_chars" : ["letter", "digit", "punctuation", "symbol"]
}
}
}
},
it basically indexes any substrings made of letters, digits, punctuation
and symbols of length 2..20.
but if that previous solution works for you, that's good :)
