Re: Substring match in search term order using Elasticsearch
For following query:
POST /my_index1/my_type1/_search
{
"query": {
"match": {
"text":
{ "query": "en's shaver",
"minimum_should_match": "100%"
}
}
}
}
I'm getting this result set -->
women's shaver
men's foil advanced shaver
women's foil advanced shaver
men's foil shaver
women's foil shaver
norelco men's foil advanced shaver
norelco women's foil advanced shaver
men's shavers
And when I search using below query:
POST /my_index1/my_type1/_search
{
"query": {
"query_string": {
"default_field": "text",
"query": "men's shaver",
"minimum_should_match": "90%"
}
}
}
I'm getting this result set -->
women's shavers
men's shaver
women's shaver
men's foil advanced shaver
women's foil advanced shaver
men's foil shaver
women's foil shaver
norelco men's foil advanced shaver
norelco women's foil advanced shaver
men's shavers
Which is not correct either.
I think shigles will not help when I want to search by substring for
example "en's" shaver.
If you think it can help then can you please post some code that I can give
me above result using shigle?

Re: Substring match in search term order using Elasticsearch
what happens when you query as you indicated ?
did you try and wildchar query ? Also perhaps an analyzer with the shingle
token filter
(http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-shingle-tokenfilter.html#analysis-shingle-tokenfilter)
will work better for your purposes ?

Substring match in search term order using Elasticsearch
Posted same question on "stackover flow"
"http://stackoverflow.com/questions/23244796/substring-match-in-search-term-order-using-elasticsearch";
but still looking for Answer.
I'm new to elasticsearch
I want to perform substring/partial word match using elastic search. I want
results to be returned in the perticular order. In order to explain my
problem I will show you how I create my index, mappings and what are the
records I use.
*Creating Index and mappings:*
PUT /my_index1
{
"settings": {
"analysis": {
"filter": {
"trigrams_filter": {
"type": "ngram",
"min_gram": 3,
"max_gram": 3
}
},
"analyzer": {
"trigrams": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"trigrams_filter"
]
}
}
}
},
"mappings": {
"my_type1": {
"properties": {
"text": {
"type": "string",
"analyzer": "trigrams"
}
}
}
}
}
*Bulk record insert:*
POST /my_index1/my_type1/_bulk
{ "index": { "_id": 1 }}
{ "text": "men's shaver" }
{ "index": { "_id": 2 }}
{ "text": "men's foil shaver" }
{ "index": { "_id": 3 }}
{ "text": "men's foil advanced shaver" }
{ "index": { "_id": 4 }}
{ "text": "norelco men's foil advanced shaver" }
{ "index": { "_id": 5 }}
{ "text": "men's shavers" }
{ "index": { "_id": 6 }}
{ "text": "women's shaver" }
{ "index": { "_id": 7 }}
{ "text": "women's foil shaver" }
{ "index": { "_id": 8 }}
{ "text": "women's foil advanced shaver" }
{ "index": { "_id": 9 }}
{ "text": "norelco women's foil advanced shaver" }
{ "index": { "_id": 10 }}
{ "text": "women's shavers" }
*Now, I want to perform search for "en's shaver". I'm searching using
follwing query:*
POST /my_index1/my_type1/_search
{
"query": {
"match": {
"text":
{ "query": "en's shaver",
"minimum_should_match": "100%"
}
}
}
}
I want results to be in following sequence:
1. men's shaver --> closest match with following same search keyword
order "en's shaver
2. women's shaver --> closest match with following same search keyword
order "en's shaver
3. men's foil shaver --> increased distance by 1
4. women's foil shaver --> increased distance by 1
5. men's foil advanced shaver --> increased distance by 2
6. women's foil advanced shaver --> increased distance by 2
7. men's shavers --> substring match for "shavers"
8. women's shavers --> substring match for "shavers"
I'm performing following query. It is not giving me result in the order I
want:
POST /my_index1/my_type1/_search
{
"query": {
"query_string": {
"default_field": "text",
"query": "men's shaver",
"minimum_should_match": "90%"
}
}
}
