This is needed for avoiding confusion between the `|` operator at `math` pipe and `|` pipe delimiter.
For example, the following query was parsed unexpectedly:
* | math foo / bar | fields x
as
* | math foo / (bar | fields) as x
Substituting `|` with `or` inside `math` pipe fixes this ambiguity.
Previously per-token hashes for per-block bloom filters were re-calculated on every scanned block.
This could be slow when the number of tokens is big or when the number of blocks to scan is big.
Pre-calculate hashes for bloom filters and then use them for searching in bloom filters.
This improves performance by 2.5x for in(...) filters with many values to search inside `in()`.
Previously (f1:foo OR f2:bar) was incorrectly returning `foo` token for `f1` and `bar` token for `f2`.
These tokens were used for checking against bloom filter for every data block, so the data block,
which didn't contain simultaneously `foo` token for `f1` field and `bar` token for `f2` field, was skipped.
This was incorrect, since such a block may contain logs matching the original OR filter.
The fix is to return common tokens from `OR`-delimted filters only if these tokens exist at EVERY such filter
for the given field name. If some `OR`-delimited filter misses the given field name, then `OR`-delimited filters
do not contain common tokens, which could be used for checking against bloom filter.
While at it, add more tests covering various edge cases for filters delimited by AND and OR.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6556
Commit adds the following changes:
* Adds support of OpenTelemetry logs for Victoria Logs with protobuf encoded messages
* json encoding is not supported for the following reasons:
- It brings a lot of fragile code, which works inefficiently.
- json encoding is impossible to use with language SDK.
* splits metrics and logs structures at lib/protoparser/opentelemetry/pb package.
* adds docs with examples for opentelemetry logs.

* updates change log
* adds VL-Debug http header
* updates doc
* extracts only the first value of http headers for VL-Stream-Fields and VL-Ignore-Fields.
It makes behaviour the same as Query string args. And allows to easily configure client applications.
Since most of the client collectors don't support multi value headers.

* Many collectors don't support forwarding url query params to the remote system. It makes impossible to define stream fields for it. Workaround with proxy between VictoriaLogs and log shipper is too complicated solution.
* This commit adds the following changes:
* Adds fallback to to headers params, if query param is empty for:
_msg_field -> VL-Msg-Field
_stream_fields -> VL-Stream-Fields
_ignore_fields -> VL-Ignore-Fields
_time_field -> VL-Time-Field
* removes deprecations from victorialogs compose files, added more
output format examples for logstash, telegraf, fluent-bit

Sometimes users may use the wrong (lower) version of Grafana when
setting up the VictoriaLogs datasource.
It would be good to document the requirements of Grafana versions to use
VictoriaMetrics/VictoriaLogs datasource.

### Describe Your Changes
Implement spellcheck command:

- add Makefile targets
This PR adds a standalone `make spellcheck` target to check `docs/*.md` files for spelling
errors. The target process is dockerized to be run in a separate npm environment.
Some `docs/` typo fixes also included.

Previously the in-memory buffer could remain unflushed for long periods of time under low ingestion rate.
The ingested logs weren't visible for search during this time.
The set of log fields in the found logs may differ from the set of log fields present in the log stream.
So compare only the log fields in the found logs when searching for the matching log entry in the log stream.
While at it, return _stream field in the delimiter log entry, since this field is used by VictoriaLogs Web UI
for grouping logs by log streams.
### Describe Your Changes
- Fixed the update of the relative time range when `Execute Query` is
clicked
- Optimized server requests: now, if an error occurs in the `/query`
request, the `/hits` request will not be executed.
#6345 (duplicates: #6440, #6312)
The TryParseTimestampRFC3339Nano() must properly parse RFC3339 timestamps with timezone offsets.
While at it, make tryParseTimestampISO8601 function private in order to prevent
from improper usage of this function from outside the lib/logstorage package.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6508
This reverts commit 92b22581e6.
Reason for revert: too complex and slow approach for spellchecking task.
This approach may significantly slow down development pace. It also may take non-trivial
amounts of additional time and resources at CI/CD because of all this npm shit at cspell directory.
Note to @arkid15r : the idea with the ability to run spellchecker on all the VictoriaMetrics
codebase is great. But this shouldn't be mandatory pre-commit check. It is enough to have
a Makefile rule like `make spellcheck`, which could be run manually whenever spellcheck is needed
(e.g. once per month or once per quarter).
- Added a bar chart displaying the number of log entries over a time
range.
#6404
- When `_msg` is empty, all fields are displayed in a single line.
- Added double quotes when copying pairs: `key: "value"`.
- Minor style adjustments.
