Elasticsearch: Search Index performance with large documents (PDF, doc, txt) slow

Question

I have an index of 65,000 documents (pdf, docx, txt, .., etc.) in the search for elasticity using the mapper binding. now I want to search the contents in this saved document using the following query:

"from" : 0, "size" : 50,
"query": {
    "match": {
        "my_attachment.content": req.params.name
     }
}

but it takes 20-30 seconds to get the results. This is a very slow answer. so what should i do for a quick response? any idea?

displayed here:

"my_attachment": {
                  "type": "attachment",
                  "fields": {
                     "content": {
                        "type": "string",
                        "store": true,
                        "term_vector": "with_positions_offsets"
                     }
                 }
}
