elasticsearch match vs term query

Question

I use the match query search for "request.method": "GET":

    {
      "query": {
        "filtered": {
          "query": {
            "match": {
              "request.method": "GET"
            }
          },
          "filter": {
            "bool": {
              "must": [
...

As expected, the Match query can get the results, as shown below:

But the question is when using the Term query, there is no results.

Update the query to change the "match" to "term", and keep the other part remain the same:

{
  "query": {
    "filtered": {
      "query": {
        "term": {
          "request.method": "GET"
        }
      },
      "filter": {
        "bool": {
          "must": [
...

I think the Term query is the "not analyzed" version of the Match query. As shown in above picture, there is at least one record has "request.method" equal to "GET". Why there is no results for the above-mentioned Term query? Thank you.

Answer 1

Assuming you are using the Standard Analyzer GET becomes get when stored in the index. The source document will still have the original "GET".

The match query will apply the same standard analyzer to the search term and will therefore match what is stored in the index. The term query does not apply any analyzers to the search term, so will only look for that exact term in the inverted index.

To use the term query in your example, change the upper case "GET" to lower case "get" or change your mapping so the request.method field is set to not_analyzed.
