hi, my use case is something like this: i m inserting some data using auto id generation. so in future i' don't know what the id it created. now if i have to insert some field in that doc, i have to search for previous fields and update that doc. i can do it using two queries search and if not exists then update. BUT my question is --\> is there any way i can do it in one query?????? thanks, subhankar -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

hi vineeth, i m very new to ES. i saw that earlier. plz correct me if i am wrong. i think that is for index request. for update api how this will work. i have to combine the query and update api both. and i think [GitHub - yakaz/elasticsearch-action-updatebyquery: ElasticSearch Update By Query action plugin](https://github.com/yakaz/elasticsearch-action-updatebyquery) will satisfy the requirement. what do you think. can you please give me a small example ??

This plugin is to update all existing documents by query. So if the document does not exist , it wont do anything. I believe what you need is "UPDATE IF EXISTS" , "CREATE IF NOT EXISTS" AFAIK this cant be done in a single query (And hence not atomic) Thanks Vineeth On Wed, May 8, 2013 at 6:24 PM, subhankar [neo20iitkgp@gmail.com](mailto:neo20iitkgp@gmail.com) wrote: > hi vineeth, > i m very new to ES. i saw that earlier. > plz correct me if i am wrong. i think that is for index request. for > update api how this will work. i have to combine the query and update api > both. > and i think > [GitHub - yakaz/elasticsearch-action-updatebyquery: ElasticSearch Update By Query action plugin](https://github.com/yakaz/elasticsearch-action-updatebyquery) will satisfy > the requirement. what do you think. can you please give me a small example > ?? > > Thanks, > subhankar > > On Wednesday, 8 May 2013 18:05:13 UTC+5:30, Vineeth Mohan wrote: > > > Just see > > Operation Type in [http://www.elasticsearch.org/](http://www.elasticsearch.org/)\*\* > > guide/reference/api/index\_/[http://www.elasticsearch.org/guide/reference/api/index\_/](http://www.elasticsearch.org/guide/reference/api/index_/) > > > > HTH > > > > Thanks > > Vineeth > > On Wed, May 8, 2013 at 5:36 PM, subhankar [neo20...@gmail.com](mailto:neo20...@gmail.com) wrote: > > > > > hi, > > > my use case is something like this: i m inserting some data using > > > auto id generation. so in future i' don't know what the id it created. > > > now if i have > > > to insert some field in that doc, i have to search for previous fields and > > > update that doc. > > > i can do it using two queries search and if not exists then > > > update. > > > BUT my question is --\> is there any way i can do it in one > > > query?????? > > > > > > thanks, > > > subhankar > > > > > > -- > > > You received this message because you are subscribed to the Google > > > Groups "elasticsearch" group. > > > To unsubscribe from this group and stop receiving emails from it, send > > > an email to elasticsearc...@\*\*[googlegroups.com](http://googlegroups.com). > > > > > > For more options, visit [https://groups.google.com/\*\*groups/opt\_out](https://groups.google.com/**groups/opt_out)[https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out) > > > . > > > > -- > > You received this message because you are subscribed to the Google Groups > > "elasticsearch" group. > > To unsubscribe from this group and stop receiving emails from it, send an > > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi , My apologies , there is one feature that you can use here , i missed it earlier. Its caled upsert. LINK - [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/update/) - Generate the docID based on the content of your feed. - Use upsert to index the document. UPSERT is like update the document or create it.

hi vineeth, thats may a solution but UPSERT always takes the doc id to process. and i m using ES auto generated id so i don't know the id in advance . ihave to any way query ES to get the uuid. so may be it is not possible. or else i have to use something like snowflake to produce the unique id and process it. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Why don't you just create an id for each document that way you don't need to deal with this. This can be something as simple as concatenating and hashing the field values so instead of doing a search for the known fields, just generate that hash and you know the exact document id. Now adding a new field will change that hash so you will need to delete the old doc and reindex with the new id. Not specifying an id is bad practice unless you never need to update/get that document again.

What is the big overhead in creating the ID yourself. Just find the hashcode or sum of content of your feed which is going to be unique for the next dupe.

thanks for ur reply and advice. i'll create the id by myself. basically i badly need a UUID generator. java native UUID generator does not guarantee of uniqueness in distributed scenario (as per my superior). is the ticketing server explained here( [http://blogs.perl.org/users/clinton\_gormley/2011/10/elasticsearchsequence---a-blazing-fast-ticket-server.html](http://blogs.perl.org/users/clinton_gormley/2011/10/elasticsearchsequence---a-blazing-fast-ticket-server.html) ) is a good idea?? thanks, subhankar On Thursday, 9 May 2013 08:49:26 UTC+5:30, Vineeth Mohan wrote: > What is the big overhead in creating the ID yourself.
