background

This PR
- Adds an optional `minimum_should_match` argument to `text_match(...)`
and wires it through the parser, planner/visitor, index bindings, and
client-level tests/examples so full-text queries can require a minimum
number of tokens to match.
Motivation
- Provide a way to require an expression to match a minimum number of
tokens in lexical search.
What changed
- Parser / grammar
- Added grammar rule and token: `MINIMUM_SHOULD_MATCH` and
`textMatchOption` in `internal/parser/planparserv2/Plan.g4`.
- Regenerated parser outputs: `internal/parser/planparserv2/generated/*`
(parser, lexer, visitor, etc.) to support the new rule.
- Planner / visitor
- `parser_visitor.go`: parse and validate the `minimum_should_match`
integer; propagate as an extra value on the `TextMatch` expression so
downstream components receive it.
- Added `VisitTextMatchOption` visitor method handling.
- Client (Golang)
- Added a unit test to verify `text_match(...,
minimum_should_match=...)` appears in the generated DSL and is accepted
by client code: `client/milvusclient/read_test.go` (new test coverage).
- Added an integration-style test for the feature to the go-client
testcase suite: `tests/go_client/testcases/full_text_search_test.go`
(exercise min=1, min=3, large min).
- Added an example demonstrating `text_match` usage:
`client/milvusclient/read_example_test.go` (example name conforms to
godoc mapping).
- Engine / index
- Updated C++ index interface: `TextMatchIndex::MatchQuery`
- Added/updated unit tests for the index behavior:
`internal/core/src/index/TextMatchIndexTest.cpp`.
- Tantivy binding
- Added `match_query_with_minimum` implementation and unit tests to
`internal/core/thirdparty/tantivy/tantivy-binding/src/index_reader_text.rs`
that construct boolean queries with minimum required clauses.
Behavioral / compatibility notes
- This adds an optional argument to `text_match` only; default behavior
(no `minimum_should_match`) is unchanged.
- Internal API change: `TextMatchIndex::MatchQuery` signature changed
(internal component). Callers in the repo were updated accordingly.
- Parser changes required regenerating ANTLR outputs
Tests and verification
- New/updated tests:
- Go client unit test: `client/milvusclient/read_test.go` (mocked Search
request asserts DSL contains `minimum_should_match=2`).
- Go e2e-style test:
`tests/go_client/testcases/full_text_search_test.go` (exercises min=1, 3
and a large min).
- C++ unit tests for index behavior:
`internal/core/src/index/TextMatchIndexTest.cpp`.
- Rust binding unit tests for `match_query_with_minimum`.
- Local verification commands to run:
- Go client tests: `cd client && go test ./milvusclient -run ^$` (client
package)
- Go testcases: `cd tests/go_client && go test ./testcases -run
TestTextMatchMinimumShouldMatch` (requires a running Milvus instance)
- C++ unit tests / build: run core build/test per repo instructions (the
change touches core index code).
- Rust binding tests: `cd
internal/core/thirdparty/tantivy/tantivy-binding && cargo test` (if
developing locally).

This commit refactors the test MilvusClient wrapper to leverage Go's
embedding pattern and improves test organization with subtests.
**File**: `tests/go_client/base/milvus_client.go`
- **Use `typeutil.NewSet` for rate limiting**: Replace map-based
`rateLogMethods` with `typeutil.NewSet` for cleaner and more efficient
membership checking
- **Embed `*client.Client` directly**: Change `MilvusClient` structure
from wrapping the client as a field to embedding it directly
- **Remove ~380 lines of wrapper methods**: All wrapper methods
(database, collection, partition, index, read/write, RBAC, etc.) are now
unnecessary thanks to Go's embedding feature, which automatically
promotes embedded methods to the outer type
- **Simplify initialization**: Update `NewMilvusClient` and `Close` to
use embedded client directly
- **Fix typo**: Correct comment "Ike the actual method" → "Invoke the
actual method"
**File**: `tests/go_client/testcases/search_test.go`
- **Wrap assertions in subtests**: Each search expression test is now
wrapped in `t.Run()` with descriptive names
- **Dynamic subtest naming**: Format:
`expr={expression}_dynamic-{true/false}` for clear test identification

This PR implements STL_SORT for VARCHAR data type for both RAM and MMAP
mode.
The general idea is that we deduplicate field values and maintains a
posting list for each unique value.
The serialization format of the index is:
```
[unique_count][string_offsets][string_data][post_list_offsets][post_list_data][magic_code]
string_offsets: array of offsets into string_data section
string_data: str_len1, str1, str_len2, str2, ...
post_list_offsets: array of offsets into post_list_data section
post_list_data: post_list_len1, row_id1, row_id2, ..., post_list_len2, row_id1, row_id2, ...
```

This pr's main goal is merge #37417 to milvus 2.5 without conflicts.
# Main Goals
1. Create and describe collections with geospatial type
2. Insert geospatial data into the insert binlog
3. Load segments containing geospatial data into memory
4. Enable query and search can display geospatial data
5. Support using GIS funtions like ST_EQUALS in query
6. Support R-Tree index for geometry type
# Solution
1. **Add Type**: Modify the Milvus core by adding a Geospatial type in
both the C++ and Go code layers, defining the Geospatial data structure
and the corresponding interfaces.
2. **Dependency Libraries**: Introduce necessary geospatial data
processing libraries. In the C++ source code, use Conan package
management to include the GDAL library. In the Go source code, add the
go-geom library to the go.mod file.
3. **Protocol Interface**: Revise the Milvus protocol to provide
mechanisms for Geospatial message serialization and deserialization.
4. **Data Pipeline**: Facilitate interaction between the client and
proxy using the WKT format for geospatial data. The proxy will convert
all data into WKB format for downstream processing, providing column
data interfaces, segment encapsulation, segment loading, payload
writing, and cache block management.
5. **Query Operators**: Implement simple display and support for filter
queries. Initially, focus on filtering based on spatial relationships
for a single column of geospatial literal values, providing parsing and
execution for query expressions.Now only support brutal search
7. **Client Modification**: Enable the client to handle user input for
geospatial data and facilitate end-to-end testing.Check the modification
in pymilvus.

>My plan is as follows.

>- [x] M2 Insert timestamptz field data
>- [x] M3 Retrieve timestamptz field data
>- [x] M4 Implement handoff
>- [x] M5 Implement compare operator

---
The third PR of issue: https://github.com/milvus-io/milvus/issues/27467,
which completes M5, M6, M7, M8 described above.
## M8 Default Timezone
We will be able to use alter_collection() and alter_database() in a
future Python SDK release to modify the default timezone at the
collection or database level.
For insert requests, the timezone will be resolved using the following
order of precedence: String Literal-> Collection Default -> Database
Default.
For retrieval requests, the timezone will be resolved in this order:
Query Parameters -> Collection Default -> Database Default.
In both cases, the final fallback timezone is UTC.
## M5: Comparison Operators
We can now use the following expression format to filter on the
timestamptz field:
- `timestamptz_field [+/- INTERVAL 'interval_string'] {comparison_op}
ISO 'iso_string' `
- The interval_string follows the ISO 8601 duration format, for example:
P1Y2M3DT1H2M3S.
- The iso_string follows the ISO 8601 timestamp format, for example:
2025-01-03T00:00:00+08:00.
- Example expressions: "tsz + INTERVAL 'P0D' != ISO
'2025-01-03T00:00:00+08:00'" or "tsz != ISO
'2025-01-03T00:00:00+08:00'".
## M6: Extract
We will be able to extract sepecific time filed by kwargs in a future
Python SDK release.
The key is `time_fields`, and value should be one or more of "year,
month, day, hour, minute, second, microsecond", seperated by comma or
space. Then the result of each record would be an array of int64.
## M7: Indexing Support
Expressions without interval arithmetic can be accelerated using an
STL-SORT index. However, expressions that include interval arithmetic
cannot be indexed. This is because the result of an interval calculation
depends on the specific timestamp value. For example, adding one month
to a date in February results in a different number of added days than
adding one month to a date in March.
---
After this PR, the input / output type of timestamptz would be iso
string. Timestampz would be stored as timestamptz data, which is int64_t
finally.
