LookupStrategy

Enums
FETCH_LIVE_DOC FETCH_LIVE_DOC strategy involves live document fetch of URLs not found in the index. Any request URL not found in the index is crawled in realtime to validate if there is a corresponding AMP URL. This strategy has higher coverage but with extra latency introduced by realtime crawling. This is the default strategy. Applications using this strategy should set higher HTTP timeouts of the API calls.
IN_INDEX_DOC IN_INDEX_DOC strategy skips fetching live documents of URL(s) not found in index. For applications which need low latency use of IN_INDEX_DOC strategy is recommended.
