6543	b9c57fb78e	Determine fuzziness of bleve indexer by keyword length (#29706) ... also bleve did match on fuzzy search and the other way around. this also fix that bug.	11 months ago
6543	1262ff6734	Refactor code_indexer to use an SearchOptions struct for PerformSearch (#29724) ... similar to how it's already done for the issue_indexer --- *Sponsored by Kithara Software GmbH*	11 months ago
6543	7fdc048153	Patch in exact search for meilisearch (#29671) ... meilisearch does not have an search option to contorl fuzzynes per query right now: - https://github.com/meilisearch/meilisearch/issues/1192 - https://github.com/orgs/meilisearch/discussions/377 - https://github.com/meilisearch/meilisearch/discussions/1096 so we have to create a workaround by post-filter the search result in gitea until this is addressed. For future works I added an option in backend only atm, to enable fuzzynes for issue indexer too. And also refactored the code so the fuzzy option is equal in logic to code indexer --- *Sponsored by Kithara Software GmbH*	11 months ago
silverwind	60e4a98ab0	Preserve BOM in web editor (#28935) ... The `ToUTF8*` functions were stripping BOM, while BOM is actually valid in UTF8, so the stripping must be optional depending on use case. This does: - Add a options struct to all `ToUTF8*` functions, that by default will strip BOM to preserve existing behaviour - Remove `ToUTF8` function, it was dead code - Rename `ToUTF8WithErr` to `ToUTF8` - Preserve BOM in Monaco Editor - Remove a unnecessary newline in the textarea value. Browsers did ignore it, it seems but it's better not to rely on this behaviour. Fixes: https://github.com/go-gitea/gitea/issues/28743 Related: https://github.com/go-gitea/gitea/issues/6716 which seems to have once introduced a mechanism that strips and re-adds the BOM, but from what I can tell, this mechanism was removed at some point after that PR.	1 year ago
Jason Song	1e76a824bc	Refactor and enhance issue indexer to support both searching, filtering and paging (#26012) ... Fix #24662. Replace #24822 and #25708 (although it has been merged) ## Background In the past, Gitea supported issue searching with a keyword and conditions in a less efficient way. It worked by searching for issues with the keyword and obtaining limited IDs (as it is heavy to get all) on the indexer (bleve/elasticsearch/meilisearch), and then querying with conditions on the database to find a subset of the found IDs. This is why the results could be incomplete. To solve this issue, we need to store all fields that could be used as conditions in the indexer and support both keyword and additional conditions when searching with the indexer. ## Major changes - Redefine `IndexerData` to include all fields that could be used as filter conditions. - Refactor `Search(ctx context.Context, kw string, repoIDs []int64, limit, start int, state string)` to `Search(ctx context.Context, options *SearchOptions)`, so it supports more conditions now. - Change the data type stored in `issueIndexerQueue`. Use `IndexerMetadata` instead of `IndexerData` in case the data has been updated while it is in the queue. This also reduces the storage size of the queue. - Enhance searching with Bleve/Elasticsearch/Meilisearch, make them fully support `SearchOptions`. Also, update the data versions. - Keep most logic of database indexer, but remove `issues.SearchIssueIDsByKeyword` in `models` to avoid confusion where is the entry point to search issues. - Start a Meilisearch instance to test it in unit tests. - Add unit tests with almost full coverage to test Bleve/Elasticsearch/Meilisearch indexer. --------- Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>	2 years ago
silverwind	88f835192d	Replace `interface{}` with `any` (#25686) ... Result of running `perl -p -i -e 's#interface\{\}#any#g' **/*` and `make fmt`. Basically the same [as golang did](2580d0e08d).	2 years ago
Jason Song	375fd15fbf	Refactor indexer (#25174) ... Refactor `modules/indexer` to make it more maintainable. And it can be easier to support more features. I'm trying to solve some of issue searching, this is a precursor to making functional changes. Current supported engines and the index versions: | engines | issues | code | | - | - | - | | db | Just a wrapper for database queries, doesn't need version | - | | bleve | The version of index is **2** | The version of index is **6** | | elasticsearch | The old index has no version, will be treated as version **0** in this PR | The version of index is **1** | | meilisearch | The old index has no version, will be treated as version **0** in this PR | - | ## Changes ### Split Splited it into mutiple packages ```text indexer ├── internal │   ├── bleve │   ├── db │   ├── elasticsearch │   └── meilisearch ├── code │   ├── bleve │   ├── elasticsearch │   └── internal └── issues ├── bleve ├── db ├── elasticsearch ├── internal └── meilisearch ``` - `indexer/interanal`: Internal shared package for indexer. - `indexer/interanal/[engine]`: Internal shared package for each engine (bleve/db/elasticsearch/meilisearch). - `indexer/code`: Implementations for code indexer. - `indexer/code/internal`: Internal shared package for code indexer. - `indexer/code/[engine]`: Implementation via each engine for code indexer. - `indexer/issues`: Implementations for issues indexer. ### Deduplication - Combine `Init/Ping/Close` for code indexer and issues indexer. - ~Combine `issues.indexerHolder` and `code.wrappedIndexer` to `internal.IndexHolder`.~ Remove it, use dummy indexer instead when the indexer is not ready. - Duplicate two copies of creating ES clients. - Duplicate two copies of `indexerID()`. ### Enhancement - [x] Support index version for elasticsearch issues indexer, the old index without version will be treated as version 0. - [x] Fix spell of `elastic_search/ElasticSearch`, it should be `Elasticsearch`. - [x] Improve versioning of ES index. We don't need `Aliases`: - Gitea does't need aliases for "Zero Downtime" because it never delete old indexes. - The old code of issues indexer uses the orignal name to create issue index, so it's tricky to convert it to an alias. - [x] Support index version for meilisearch issues indexer, the old index without version will be treated as version 0. - [x] Do "ping" only when `Ping` has been called, don't ping periodically and cache the status. - [x] Support the context parameter whenever possible. - [x] Fix outdated example config. - [x] Give up the requeue logic of issues indexer: When indexing fails, call Ping to check if it was caused by the engine being unavailable, and only requeue the task if the engine is unavailable. - It is fragile and tricky, could cause data losing (It did happen when I was doing some tests for this PR). And it works for ES only. - Just always requeue the failed task, if it caused by bad data, it's a bug of Gitea which should be fixed. --------- Co-authored-by: Giteabot <teabot@gitea.io>	2 years ago
