[dependabot]

Updates the requirements on tantivy to permit the latest version.

Changelog

Sourced from tantivy's changelog.

Tantivy 0.20.2

• Align numerical type priority order on the search side. #2088 (@​fmassot)
• Fix is_child_of function not considering the root facet. #2086 (@​adamreichhold)

Tantivy 0.20.1

• Fix building on windows with mmap #2070 (@​ChillFish8)

Tantivy 0.20

Bugfixes

• Fix phrase queries with slop (slop supports now transpositions, algorithm that carries slop so far for num terms > 2) #2031#2020(@​PSeitz)
• Handle error for exists on MMapDirectory #1988 (@​PSeitz)
• Aggregation
  • Fix min doc_count empty merge bug #2057 (@​PSeitz)
  • Fix: Sort order for term aggregations (sort order on key was inverted) #1858 (@​PSeitz)

Features/Improvements

• Add PhrasePrefixQuery #1842 (@​trinity-1686a)
• Add coerce option for text and numbers types (convert the value instead of returning an error during indexing) #1904 (@​PSeitz)
• Add regex tokenizer #1759(@​mkleen)
• Move tokenizer API to seperate crate. Having a seperate crate with a stable API will allow us to use tokenizers with different tantivy versions. #1767 (@​PSeitz)
• Columnar crate: New fast field handling (@​fulmicoton @​PSeitz) #1806#1809
  • Support for fast fields with optional values. Previously tantivy supported only single-valued and multi-value fast fields. The encoding of optional fast fields is now very compact.
  • Fast field Support for JSON (schemaless fast fields). Support multiple types on the same column. #1876 (@​fulmicoton)
  • Unified access for fast fields over different cardinalities.
  • Unified storage for typed and untyped fields.
  • Move fastfield codecs into columnar. #1782 (@​fulmicoton)
  • Sparse dense index for optional values #1716 (@​PSeitz)
  • Switch to nanosecond precision in DateTime fastfield #2016 (@​PSeitz)
• Aggregation
  • Add date_histogram aggregation (only fixed_interval for now) #1900 (@​PSeitz)
  • Add percentiles aggregations #1984 (@​PSeitz)
  • [breaking] Drop JSON support on intermediate agg result (we use postcard as format in quickwit to send intermediate results) #1992 (@​PSeitz)
  • Set memory limit in bytes for aggregations after which they abort (Previously there was only the bucket limit) #1942#1957(@​PSeitz)
  • Add support for u64,i64,f64 fields in term aggregation #1883 (@​PSeitz)
  • Allow histogram bounds to be passed as Rfc3339 #2076 (@​PSeitz)
  • Add count, min, max, and sum aggregations #1794 (@​guilload)
  • Switch to Aggregation without serde_untagged => better deserialization errors. #2003 (@​PSeitz)
  • Switch to ms in histogram for date type (ES compatibility) #2045 (@​PSeitz)
  • Reduce term aggregation memory consumption #2013 (@​PSeitz)
  • Reduce agg memory consumption: Replace generic aggregation collector (which has a high memory requirement per instance) in aggregation tree with optimized versions behind a trait.
  • Split term collection count and sub_agg (Faster term agg with less memory consumption for cases without sub-aggs) #1921 (@​PSeitz)
  • Schemaless aggregations: In combination with stacker tantivy supports now schemaless aggregations via the JSON type.
    • Add aggregation support for JSON type #1888 (@​PSeitz)
    • Mixed types support on JSON fields in aggs #1971 (@​PSeitz)
  • Perf: Fetch blocks of vals in aggregation for all cardinality #1950 (@​PSeitz)
  • Allow histogram bounds to be passed as Rfc3339 #2076 (@​PSeitz)
• Searcher with disabled scoring via EnableScoring::Disabled #1780 (@​shikhar)
