So I have an index with the synonym mapping defined in the search analyzer. When I first created the index, the synonyms were picked up on search. After that, I updated the synonyms.txt files on the nodes once to update a synonym mapping and restarted each node after making a change. This caused the synonym change to be reflected on search thoughout the index.

Now, when I change the synonyms file and restart the nodes, the synonym mapping isn't updating as I believe it should. Am I missing something? I thought since the synonym mapping was on a search\_analyzer I wouldn't have to reindex each time to reflect the changes.

Here is my index definition:

> ```
> PUT /synonym_index
> {
> "aliases": {},
> "mappings": {
> "_doc": {
> "properties": {
> "name": {
> "type": "text",
> "fields": {
> "english": {
> "type": "text",
> "analyzer": "english",
> "search_analyzer":"english_and_synonyms"
> }
> }
> }
> }
> }
> },
> "settings": {
> "analysis": {
> "analyzer": {
> "english": {
> "tokenizer": "standard",
> "filter": [
> "english_possessive_stemmer",
> "lowercase",
> "english_stop",
> "english_keywords",
> "english_stemmer"
> ]
> },
> "english_and_synonyms": {
> "tokenizer": "standard",
> "filter": [
> "search_synonyms",
> "english_possessive_stemmer",
> "lowercase",
> "english_stop",
> "english_keywords",
> "english_stemmer"
> ]
> }
> },
> "filter": {
> "english_stop": {
> "type": "stop",
> "stopwords": "_english_" 
> },
> "english_keywords": {
> "type": "keyword_marker",
> "keywords": ["example"] 
> },
> "english_stemmer": {
> "type": "stemmer",
> "language": "english"
> },
> "english_possessive_stemmer": {
> "type": "stemmer",
> "language": "possessive_english"
> },
> "search_synonyms" : {
> "type" : "synonym_graph",
> "synonyms_path" : "analysis/synonyms.txt"
> }
> }
> },
> "index": {
> "number_of_shards": "5",
> "number_of_replicas": "1"
> }
> }
> }
> 
> ```

I've tried restarting the node with

> sudo service elasticsearch restart

and also with

> sudo service elasticsearch stop  
> sudo service elasticsearch start

but neither are causing my changes to reflect.
