[−][src]Struct tantivy::IndexReader
IndexReader
is your entry point to read and search the index.
It controls when a new version of the index should be loaded and lends
you instances of Searcher
for the last loaded version.
Clone
does not clone the different pool of searcher. IndexReader
just wraps and Arc
.
Methods
impl IndexReader
[src]
pub fn reload(&self) -> Result<()>
[src]
Update searchers so that they reflect the state of the last
.commit()
.
If you set up the OnCommit
ReloadPolicy
(which is the default)
every commit should be rapidly reflected on your IndexReader
and you should
not need to call reload()
at all.
This automatic reload can take 10s of milliseconds to kick in however, and in unit tests it can be nice to deterministically force the reload of searchers.
pub fn searcher(&self) -> LeasedItem<Searcher>
[src]
Returns a searcher
This method should be called every single time a search
query is performed.
The searchers are taken from a pool of num_searchers
searchers.
If no searcher is available
this may block.
The same searcher must be used for a given query, as it ensures the use of a consistent segment set.
