HI Team, As we know 'AN' is stopword in Elastic search. I have executed the below query. { “from”: 0, “size”: 100, “query”: { “bool”: { “must”: [ { “match”: { “receiver”: { “query”: “AN”, “type”: “boolean” } } } ] } } } The query returns an empty results even though the document is available in ES ES has the below document { \_index: messages \_type: ABCType \_id: 4571b1a9-d0eb-4e98-bc3f-562d2ee8e206 \_version: 1 \_score: 1 \_source: { sender\_name: Unknown receiver: AN } } here, What could be the best way to disable the stopword 'AN' only. Which analyzer i should use? Were to configure the analyzer? ---

Thank you so much. Here I just need to disable only one stopword. So I will follow the above link and can create the analyzer.But, after adding the analyzer to index, does it really affects ES performance? ---

There is no way to remove a stopword, you need to redefine a standard analyzer and provide the whole list of stop words that you need. [https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-standard-analyzer.html#\_configuration](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-standard-analyzer.html#_configuration) Here is the current list: [https://github.com/apache/lucene-solr/blob/e2521b2a8baabdaf43b92192588f51e042d21e97/lucene/core/src/java/org/apache/lucene/analysis/standard/StandardAnalyzer.java#L45](https://github.com/apache/lucene-solr/blob/e2521b2a8baabdaf43b92192588f51e042d21e97/lucene/core/src/java/org/apache/lucene/analysis/standard/StandardAnalyzer.java#L45) ---

the idea here is to use your own "stop words" list which does not include the ones you don't want, instead of using the standard "stop words" list. Once you define your own, you need to define your own "analyzer" and apply or use it where it is appropriate. ---

Thank you so much, guys. The below code snippet am going to use, is that fine? Also, What about the performance issues? index : analysis : analyzer : default : type : standard stopwords : [ "a", "and", "are", "as", "at", "be", "but", "by", "for", "if", "in", "into", "is", "it", "no", "not", "of", "on", "or", "such", "that", "the", "their", "then", "there", "these", "they", "this", "to", "was", "will", "with"] Note: I am using ES version 1.3.4 only. ---

the performance should not be worse than a longer stop words list (if I have to guess) ---

Thank you so much, @thn . Also, Can any one from elastic team confirms that the above one is correct? ---
