Hi,
I'm using following analyzers for indexing my documents in ES:
"analysis" : {
"analyzer" : {
"str_search_analyzer" : {
"tokenizer" : "standard",
"filter" : ["lowercase","asciifolding"]
},
"str_index_analyzer" : {
"tokenizer" : "standard",
"filter" : ["lowercase","asciifolding","edgengram"]
}
},
"filter" : {
"edgengram" : {
"type" : "edgeNGram",
"min_gram" : 3,
"max_gram" : 20,
"side" : "front"
}
}
}
I'm sure the search and index analyzers can serve my pupose well but
querying documents in a right manner is also necessary for better results.
I have read different queries which have been provided by ES but confused
on which query or a combination of queries can work well with my use case.
Let's say I have a document which contains 3 fields:
city_name: Palo Alto
state_name: California
country: United States
Now, my index analyzer will create following tokens on these 3 fields:
city_name: pal, palo, alt, alto
state_name: cal, cali, calif, califo, califor, californ, californi,
california
country: uni, unit, unite, united, sta, stat, state, states
And user search for a word like: palo alt
now, my search analyzer will index it like: palo, alt
Now, I want to return only those documents which contains both these
tokens, either in same field(like state, city or country) or as a
combination of 2 fields. (Not those documents where either palo or pal or
alt are present. )
Now which query can give me better results with these types of indexing and
searching ?
I read about terms query but that works on not anlyzed fields. Also,
querystring will generate some inbuilt regex queries for searching (I don't
want that) I want only those documents where all the tokens of a user
searched query are present in either same fields or multiple fields within
same document. How can I achieve this ?
Any idea ?
Thanks
