You can deploy content to a live AVM store which is searchable.
In 3.2 this is what the "avm" deployment target is for. You may also find documentation on "ASRs".
Going forward in 3.3, although the ASR approach will still work, and you are still able to do whatever fits best for your requirements and architecture, alfresco will be recommend deploying to a DM repository and then use the CMIS API to access your WCM content.
