- Change in the DocSet and Scorer API. (@fulmicoton).
A freshly created DocSet point directly to their first doc. A sentinel value called TERMINATED marks the end of a DocSet.
`.advance()` returns the new DocId. `Scorer::skip(target)` has been replaced by `Scorer::seek(target)` and returns the resulting DocId.
As a result, iterating through DocSet now looks as follows
```rust
let mut doc = docset.doc();
while doc != TERMINATED {
// ...
doc = docset.advance();
}
```
The change made it possible to greatly simplify a lot of the docset's code.
- Misc internal optimization and introduction of the `Scorer::for_each_pruning` function. (@fulmicoton)
In order to make `IndexWriter::run` callable from outside of the create,
the `UserOperation` type needs to be publicly available.
Since the `indexer` module is private, we just export the `UserOperation`
type directly.
* WIP implemented is_compatible
hide Footer::from_bytes from public consumption - only found Footer::extract
used outside the module
Add a new error type for IncompatibleIndex
add a prototypical call to footer.is_compatible() in ManagedDirectory::open_read
to make sure we error before reading it further
* Make error handling more ergonomic
Add an error subtype for OpenReadError and converters to TantivyError
* Remove an unnecessary assert
it's follower by the same check that Errors instead of panicking
* Correct the compatibility check logic
Leave a defensive versioned footer check to make sure we add new logic handling
when we add possible footer versions
Restricted VersionedFooter::from_bytes to be used inside the crate only
remove a half-baked test
* WIP.
* Return an error if index incompatible - closes#662
Enrich the error type with incompatibility
Change return type to Result<bool, TantivyError>, instead of bool
Add an Incompatibility enum that enriches the IncompatibleIndex error variant
with information, which then allows us to generate a developer-friendly hint how
to upgrade library version or switch feature flags for a different compression
algorithm
Updated changelog
Change the signature of is_compatible
Added documentation to the Incompatibility
Added a conditional test on a Footer with lz4 erroring
* Add a doctest to BooleanQuery
Closes#446
Mark a function that is only used in tests to be compiled for tests only
Fix doc-comments in a couple of related files
* Minor corrections
remove whitespace, fix typos, add explicit dyn marker
* WIP: BooleanQuery doc test
Trying to nest several BooleanQueries together
* Addressed old review
rust 2018 edition + make function available to everyone
* Box the previous query to resolve the type error
* Rework wording in DocAdress document strings
* Reworded and restructured the docstring
* add basic support for float
as for i64, they are mapped to u64 for indexing
query parser don't work yet
* Update value.rs
* implement support for float in query parser
* Update README.md
* initial version, still a work in progress
* remove redudant or
* add chrono::DateTime and index i64
* add more tests
* fix tests
* pass DateTime by ptr
* remove println!
* document query_parser rfc 3339 date support
* added some more docs about implementation to schema.rs
* enforce DateTime is UTC, and re-export chrono
* added DateField to changelog
* fixed conflict
* use INDEXED instead of INT_INDEXED for date fields
* Moving lock to directory/
* added fs2
* doc
* Using fs2 for locking
* Added unit test
* Fixed error message related unit test
* Fixing location of import
* Split Collector into an overall Collector and a per-segment SegmentCollector. Precursor to cross-segment parallelism, and as a side benefit cleans up any per-segment fields from being Option<T> to just T.
* Attempt to add MultiCollector back
* working. Chained collector is broken though
* Fix chained collector
* Fix test
* Make Weight Send+Sync for parallelization purposes
* Expose parameters of RangeQuery for external usage
* Removed &mut self
* fixing tests
* Restored TestCollectors

* using crossbeam::channel
* inlining
* Comments about panics propagating
* Added unit test for executor panicking
* Readded default
* Removed Default impl
* Added unit test for executor
* Compute space usage of a Searcher / SegmentReader / CompositeFile
* Fix typo
* Add serde Serialize/Deserialize for all the SpaceUsage structs
* Fix indexing
* Public methods for consuming space usage information
* #281: Add a space usage method that takes a SegmentComponent to support code that is unaware of particular segment components, and to make it more likely to update methods when a new component type is added.
* Add support for space usage computation of positions skip index file (#281)
* Add some tests for space usage computation (#281)
