"Deploy" lucene index to GAE

[Alexandr Savochkin]

Hello!

I am going to use it in small personal GAE project related to chemical compounds articles search in wikipedia.

It is more convinient for me to index data locally and then somehow "transfer" index to GAE. Is it possible wth Lucene AppEngine? How should I do this? Or may be I should use another approach to deploying index on GAE?

I have expirience with Java+Lucene, but I am quite new in Google App Engine.
Thank you.

Hello!

Unfortunately there isn't a specific migration tool for LAE. LAE is designed to be like any other Lucene Directory, it means that you can use any existing importing tool that directly uses the Lucene api (as long as the importing tool does not broke any GAE principle/limitation). For your specific case I think you have two alternatives:

1. Include only one time in your GAE application the index (files etc..) and create a job that, reading from the existing one, writes into the LAE index/lucene directory: this can be done only if your existing index is not too big.
2. Create an http/rest service on your GAE application useful to populate your LAE index, by doing that you can run a standalone importer from everywhere (this can be a very good contribution into the LAE ecosystem);

Thank you for using LAE!
