Hello, I have a collection of strings with ordered user events, produced by a 3rd party system, that looks like this: USER A -\> 10:1 11 10:2 10:3 1201:1 USER B -\> 10:1 10:2 10:3 10:4 , where every word is an event, generated by that user. Event has a following format: \\:\ With ElasticSearch I want to count all documents (users) that have a certain sequence of events: 10 -\> 10 -\> 10 10:1 -\> 10:3 11 -\> 1201 In some cases I need to search by event ID, only - item ID and amount are optional. What is the proper way to achieve that in ElasticSearch? Currently, I store those sequences in MongoDB, and perform search/count with complex regexes.

Not quite sure I understand 100% the requirements. So if I have these 2 documents: Doc 1 -\> 10:1 11 10:2 10:3 1201:1 Doc 2 -\> 10:1 10:2 10:3 10:4 What would each of these queries return? 1. 10 11 10 2. 10 10 10 3. 10 10 11 4. 10 12 5. 10:3 1201 -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
