266788be14 app/vmselect: use storage.NewSearchQuery() instead of constructing storage.SearchQuery in-place 
This should prevent from bugs when AccountID and ProjectID aren't set in storage.SearchQuery.

82973f8ae7 Revert "lib/storage: remove unused fetchData arg from BlockRef.MustReadBlock" 
This reverts commit bab6a15ae0.

Reason for revert: the `fetchData` arg is used in cluster branch.
Leaving this arg in master branch makes smaller the diff with cluster branch.

8d9eb5f808 lib/storage: mention time range used in the query that led to error message 
This should improve detecting slow queries with too big time ranges

039c9d2441 lib/storage: respect -search.maxQueryDuration when searching for time series in inverted index 
Previously the time spent on inverted index search could exceed the configured `-search.maxQueryDuration`.
This commit stops searching in inverted index on query timeout.

d5dddb0953 all: use %w instead of %s for wrapping errors in fmt.Errorf 
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

b4afe562c1 lib/storage: postpone reading data from blocks during search 
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.

This improves single-node VM performance on heavy queries by up to 2x.

d68546aa4a lib/storage: pre-fetch metricNames for the found metricIDs in Search.Init

20812008a7 lib/storage: remove metricID with missing metricID->metricName entry 
The metricID->metricName entry can be missing in the indexdb after unclean shutdown
when only a part of entries for new time series is written into indexdb.

Recover from such a situation by removing the broken metricID. New metricID
will be automatically created for time series with the given metricName
when new data point will arive to it.
