Elasticsearch: Full match of query value from beginning to end of field - elasticsearch

Question

I have problem with full match querying of field value. title and gender - fields of indexed docs
query: {
query_string: {
query: "box AND gender:\"women\"",
default_field: "title"
}
}
I use double quotes to match full query for gender. But if there is gender "men,women" with title 'box' it also will be in results. I know, that elasticsearch does not support regexp characters ^ and $ for beginning and end of the string, so I couldn't make /^women$/.
What do I need to do if I want docs matching only 'women' gender, not 'men,women' ?

For exact searches you should use a terms query rather than a fulltext-search query like the query_string. So to get all documents that matches exactly gender == women you should do it like so:
GET your-index/_search
{
"query": {
"bool": {
"must": [
{
"term": {
"gender.keyword": {
"value": "women"
}
}
}
]
}
}
}
Please be aware that this query assumes that the gender-field is also mapped as a keyword.
To complete the query you would add another must-clause to get all documents that have box in the title field women as the value of the gender-field.
GET your-index/_search
{
"query": {
"bool": {
"must": [
{
"term": {
"gender.keyword": {
"value": "women"
}
}
},
{
"match": {
"title": "box"
}
}
]
}
}
}

Thank you apt-get_install_skill. Keyword did the work, but with some addings.
Summary this is solution:
query: {
bool: {
must: {
query_string: {
query: "box",
default_field: "title"
}
},
filter: {
bool: {
should: [
{term: {"gender.keyword": "women"}}
]
}
}
}
}
I need should as array for searching multiple genders if I will need it. For example, some docs have unisex gender, such as 'women,men'
Example with multiple genders:
query: {
bool: {
must: {
query_string: {
query: "box",
default_field: "title"
}
},
filter: {
bool: {
should: [
{term: {"gender.keyword": "women"}},
{term: {"gender.keyword": "kids"}}
#summary it may be gender 'girls'
]
}
}
}
}
