Hi Dan,
Not sure whether i have same understanding "*edge n-gram filter at search
time*" refer to apply edge n-gram filter in the query ? If this is the case
i think i didn't apply any analyzer in the query :
*Here my query : *
{
"query" : {
"multi_match": {
"query": "happy",
"fields": [ "DISPLAY_NAME.AUTOCOMPLETE" ]
}
},
"sort" : [{
"_score" : { "order" : "desc"},
"DISPLAY_NAME.NAME" : { "order" : "asc" }}]
}
*The result : *
https://gist.github.com/cheehoo/11371837
As you notice in the result it returned :
Happenings
Happier?
which aren't part of what i searched for.
*The mapping : *
https://gist.github.com/cheehoo/11371897
*The index : *
{
"jdbc_dev": {
"settings": {
"index.number_of_shards": "5",
"index.number_of_replicas": "1",
"index.version.created": "900299",
"index.analysis.filter.my_edge_ngram_filter.type": "edgeNGram",
"index.analysis.analyzer.edge_ngram_keyword_lowercase_analyzer.filter.1":
"lowercase",
"index.analysis.analyzer.edge_ngram_keyword_lowercase_analyzer.filter.0":
"my_edge_ngram_filter",
"index.analysis.analyzer.edge_ngram_keyword_lowercase_analyzer.tokenizer":
"keyword",
"index.analysis.filter.my_edge_ngram_filter.min_gram": "2",
"index.analysis.filter.my_edge_ngram_filter.max_gram": "30"
}
}
}
After that with Adrien suggestion i tried create the analyzer
"analysis" : {
"analyzer" : {
"keyword_lowercase_analyzer" : {
"tokenizer" : "keyword",
"filter" : ["lowercase"]
}
}
}
and recreate the mapping with :
"DISPLAY_NAME": {
"type": "string",
"search_analyzer" : "keyword_lowercase_analyzer"
}
however with this configuration it wasn't able to search via "hap" to
return the following result :
*1)Happy*
*2)Happy birthday*
*3)Happy valentine*
Thanks
