not able to search in compounding query using analyzer - elasticsearch

Question

I have a problem index which has multiple fields e.g tags (comma separated string of tags), author, tester. I am creating a global search where problems can be searched by all these fields at once.
I am using boolean query
e.g
{
"query": {
"bool": {
"must": [{
"match": {
"author": "author_username"
}
},
{
"match": {
"tester": "tester_username"
}
},
{
"match": {
"tags": "<tag1,tag2>"
}
}
]
}
}
}
Without Analyzer I am able to get the results but it uses space as separator e.g python 3 is getting searched as python or 3.
But I wanted to search Python 3 as single query. So, I have created an analyzer for tags so that every comma-separated tag is considered as one, not by standard whitespace.
{
"settings": {
"analysis": {
"analyzer": {
"my_analyzer": {
"tokenizer": "my_tokenizer"
}
},
"tokenizer": {
"my_tokenizer": {
"type": "pattern",
"pattern": ","
}
}
}
},
"mappings": {
"properties": {
"tags": {
"type": "text",
"analyzer": "my_analyzer",
"search_analyzer": "standard"
}
}
}
}
But now I am not getting any results. Please let me know what I am missing here. I am not able to find the use of analyzer in compound queries in the documentation: https://www.elastic.co/guide/en/elasticsearch/reference/current/compound-queries.html
Adding an example:
{
"query": {
"bool": {
"must": [{
"match": {
"author": "test1"
}
},
{
"match": {
"tester": "test2"
}
},
{
"match": {
"tags": "test3, abc 4"
}
}
]
}
}
}
Results should match all the fields but for the tags field there should be a union of tags and query should be comma-separated not by space. i.e query should match test and abc 4 but above query searching for test, abc and 4.

You need to either remove search_analyzer from your mapping or pass my_analyzer in match query
GET tags/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"tags": {
"query": "python 3",
"analyzer": "my_analyzer" --> by default search analyzer is used
}
}
}
]
}
}
}
By default, queries will use the analyzer defined in the field mapping, but this can be overridden with the search_analyzer setting.
