How to make a query could match Possessive Case?

Elastic Stack Elasticsearch
1

Hi there,

I used default settings to create the indices on my data,while I found that
queries could not match Possessive Case.
For example, when I make a matchPhrasequery("Aharon Barak"), the documents
including strings such as "Aharon Barak's wife".
I have known that I need to set the word delimiter tokenfilter：
http://www.elasticsearch.org/guide/reference/index-modules/analysis/word-delimiter-tokenfilter/

From my understanding, I need to create the indices again after I change
the settings.
Is there any convenient means to handle this problem?

Also, I'm using ES 0.90.Beta

You do have to rebuild the index. There are currently no schema migrations
for Elasticsearch.
If it isn't convenient to re-generate the data, you could do a scan of the
old index and insert each document into new index (server).

Thank you, Taras.
I have checked the word delimiter tokenfilter description.
Should I explicitly set it when put mapping? Would ES set it as default
settings?
