I'm looking at using Elasticsearch to provide the search functions of  
our site.

I've been experimenting with it but am unable to enable the porterstem  
analyser (so that a search for fight matches fights and fighting).

Here's a run down of my input.

```
curl -XPUT localhost:9200/local/ -d'
index :
    analysis :
        analyzer :
            stemming :
                type : custom
                tokenizer : standard
                filter : [standard, lowercase, stop, porterStem]
'

curl -XPUT localhost:9200/local/_mapping -d'{"properties":

```

{ "title" : { "analyzer" : "stemming", "type" : "string" }}}'

```
curl -XPUT localhost:9200/local/article/1 -d'{"title": "Fight for

```

your life"}'  
curl -XPUT localhost:9200/local/article/2 -d'{"title": "Fighting  
for your life"}'  
curl -XPUT localhost:9200/local/article/3 -d'{"title": "My dad  
fought a dog"}'  
curl -XPUT localhost:9200/local/article/4 -d'{"title": "Bruno  
fights Tyson tomorrow"}'

However running a search for 'fight' only matches the first entry -  
the one that contains the exact term.

```
curl -XGET localhost:9200/local/_search?q=fight

```

The correct settings appear to have been set up but doesn't seem to  
work.

```
  "indices" : {
    "local" : {
      "aliases" : [],
      "settings" : {
        "index.analysis.analyzer.stemming.type" : "custom",
        "index.analysis.analyzer.stemming.tokenizer" : "standard",
        "index.analysis.analyzer.stemming.filter.1" : "lowercase",
        "index.analysis.analyzer.stemming.filter.0" : "standard",
        "index.analysis.analyzer.stemming.filter.3" :

```

"porterStem",  
"index.analysis.analyzer.stemming.filter.2" : "stop",  
"index.number\_of\_shards" : "5",  
"index.number\_of\_replicas" : "1"  
},

Anyone got this functionality up and running and able to point me in  
the right direction?

Here is a gist with a sample of how ti works: [gist:879883 · GitHub](https://gist.github.com/879883).

Few notes on what you do:

1. The put mapping should be on index and type, PUT localhost:9200/local/article/\_mapping.
2. The body of put mapping should include the type as top level.
3. By default, when searching without specifying on a specific field, the \_all field is searched, and thats not stemmed based on the mappings, only title is stemmed.

Hi,

I had a similar problem with the Snowball analyzer. With Shay's help I  
was able to get it running. You can find the example here:

Thanks. I've got it up and running now thanks to the gist. Is there  
anyway to apply the index level mapping through a config file (json or  
yaml)?
