I am using elasticsearch to find similar documents. Below is the query I am using:
```
{
"query": {
"more_like_this":{
"like": {
"_index": "docs",
"_type": "pdfs",
"_id": "pdf_1"
},
"min_term_freq": 1,
"min_doc_freq": 1,
"max_query_terms: 50,
"minimum_should_match": "50%"
}
}
}
```
I am extracting the text from PDF and storing in my index "docs". Below are the mappings for type "pdfs":
```
{
"properties": {
"content":{
"type": "string",
"analyzer": "my_analyzer"
}
}
}
```
In the result sets I am getting similar documents with their scores. Based on what I have read so far it is not possible to calculate percentage similarity based on score so I am not trying to do that. I am trying to figure out if it is possible to know:
"Out of 50 query terms from the source document how many terms are matched in a document? or percentage of terms matched?"
As you can see that in my query I am specifying minimum\_should\_match as 50% so I am assuming that elasticsearch is filtering the documents somewhere based on the how much percentage of terms are matched in a document. I want to get that percentage. I am fairly new to elasticsearch. So far I have gone through the documentation but couldn't find out how to do it. Any pointer/help is appreciated!
