Hi.  
My elastic search was working fine before I tried to configure cache  
filter. I tried to do this -\>

curl -XPUT localhost:9200/twitter/\_settings -d  
{  
"index" : {  
"number\_of\_replicas" : 4, "type":  
"node" ,"index.cache.filter.max\_size" : "20%" ,  
"index\_cache\_field\_expiry" : "5m"  
}  
}

And now I am unable to run evan a simple query. I get the message -\>  
{  
"error" : "SearchPhaseExecutionException[Failed to execute phase  
[query], total failure; shardFailures {[_na_][twitter][0]: No active  
shards}{[_na_][twitter][1]: No active shards}{[_na_][twitter][2]: No  
active shards}{[_na_][twitter][3]: No active shards}{[_na_][twitter]  
[4]: No active shards}]",  
"status" : 500  
}

Can somebody please help to understand what I did and how to fix it?

Regards.

In logs I am getting this.

Ok. I reinstalled Elasticsearch and did this

curl -XPUT localhost:9200/twitter/\_settings -d '  
{  
"index" : {  
"number\_of\_replicas" : 4, "type":  
"node" ,"index.cache.filter.max\_size" : "20%" ,  
"index\_cache\_field\_expiry" : "5m"  
}

} '

Then I did some changes in my elasticsearch.yml file. What i did was

index :  
analysis :  
analyzer :  
analyzer1 :  
type : custom  
tokenizer : tokenizer1  
filter : [filter2 , filter1 , filter5 , filter3]  
char\_filter : char\_filter1  
tokenizer :  
tokenizer1 :  
type : pattern  
pattern : "(\W\*,\W\*)|(\W_OR\W_)|(\W_AND\W_)|(\W\W\*)|(\d  
\d\*)"  
filter :  
filter1 :  
type : stop  
stopwords\_path : "stopwords.txt"  
filter2 :  
type : lowercase  
filter3 :  
type : synonym  
synonyms\_path : "/home/nachiket/Softwares/elasticsearch-0.16.2/  
config/synonym.txt"  
filter4 :  
type : stemmer  
language : minimal\_english  
filter5 :  
type : shingle  
max\_shingle\_size : 4  
char\_filter :  
char\_filter :  
char\_filter1 :  
type : html\_strip  
escaped\_tags : [xxx , yyy]  
read\_ahead : 1024

And I again started getting error message after any query:  
{"error":"SearchPhaseExecutionException[Failed to execute phase  
[query], total failure; shardFailures {[_na_][twitter][0]: No active  
shards}{[_na_][twitter][1]: No active shards}{[_na_][twitter][2]: No  
active shards}{[_na_][twitter][3]: No active shards}{[_na_][twitter]  
[4]: No active shards}]","status":500}

I am stuck in the middle of my work. Can somebody please help me with  
it ???

Regards.

How many nodes are you running? Do you see failures in the logs, you might be misconfiguring the index and it fails to create the shards.

Thanks a lot.  
I have just started looking into how to index and search with Elastic Search.  
But I couldn't find how to configure the index. I used one code from one of the replies on another topic.  
Can you tell me where to find it out?

When I am doing for new index  
curl -XPUT localhost:9200/twitter2 -d '{  
"settings" : {  
"index" : {  
"number\_of\_shards" : 1,  
"number\_of\_replicas" : "4"  
}  
}  
}'  
It is correctly indexing and searching.

But when I do it for existing index  
curl -XPUT localhost:9200/twitter -d '{  
"settings" : {  
"index" : {  
"number\_of\_shards" : 1,  
"number\_of\_replicas" : "4"  
}  
}  
}'  
It is giving  
{"error":"IndexAlreadyExistsException[[twitter] Already  
exists]","status":400}. How can I configure my index??

You need to delete the index and create a new one.

You can use index aliases to make this transparent to your main  
application (ie the main app uses an alias which points to the current  
index, then you can change the real index in the background, and just  
update the alias)

Hi. I made an alias for my index and changed name of index to wherever  
I wrote twitter.  
Then I deleted my twitter index to put setting  
curl -XPUT localhost:9200/twitter -d '{  
"settings" : {  
"index" : {  
"number\_of\_shards" : 1,  
"number\_of\_replicas" : "4"  
}  
}  
}'

But my data was lost as soon as I deleted the main twitter index.  
Though it was not a big loss for now for future references can you  
elaborate on how to do following:  
(the main application uses an alias which points to the current  
index, then you can change the real index in the background, and just  
update the alias)

- create index twitter\_20110701
- create alias 'twitter' which points to twitter\_20110701
- your app uses the index 'twitter'

now you need to change the mapping

- create index twitter\_20110702
- reindex your data from twitter\_20110701 to twitter\_20110702
- update alias 'twitter' to point to twitter\_20110702
- delete index twitter\_20110701

Alternatively, if your old data doesn't need to be reindexed with the  
new mapping, you can have two aliases:

- twitter\_write (points to current index)
- twitter\_read (points to current index and older indices)

The docs could be better than they are, but all of the information is  
available from here: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/)
