Im working with Meteor and MongoDB

The index with all properties are set.  
Now i wanna add to every Property field the Analyzer

example with one field (doesnt work, because the field "title" already exist)  
\> PUT easysearch/\_mapping/projects  
\> {  
\> "properties": {  
\> "title": {  
\> "type": "text",  
\> "analyzer": "myAnalyzer",  
\> "search\_analyzer": "standard"  
\> }  
\> }  
\> }

the Analyzer is already set:

```
> PUT /easysearch/_settings
> {
> "settings" : {
> "analysis" : {
> "analyzer" : {
> "myAnalyzer" : {
> "type" : "custom",
> "tokenizer" : "whitespace",
> "filter" : ["split_on_numerics"]
> }
> },
> "filter" : {
> "split_on_numerics" : {
> "type" : "word_delimiter",
> "split_on_numerics" : true,
> "split_on_case_change" : true,
> "generate_word_parts" : true,
> "generate_number_parts" : true,
> "catenate_words" : true
> }
> }
> }
> }
> }

```

You cannot alter things like this after they already exist (ie have data in them).  
You will need to reindex to have this applied.
