From 9dcdf2e9ca8badf5fac24ef79d775a858d1ae6fe Mon Sep 17 00:00:00 2001 From: Jennifer Davis Date: Tue, 3 Nov 2026 23:31:50 +0000 Subject: [PATCH] feat(bigquery): add bigquery_search_with_text_analyzer sample to search text using a specified text analyzer Problem: The BigQuery documentation (https://cloud.google.com/bigquery/docs/search) needs a standalone, tested Python code sample demonstrating how to search text using a specified text analyzer (region tag `bigquery_search_with_text_analyzer`). Solution: - Add `search_with_text_analyzer(project_id: str) -> None` in `bigquery/search/bigquery_search_with_text_analyzer.py` (Run a BigQuery SEARCH query specifying an explicit text analyzer such as LOG_ANALYZER, NO_OP_ANALYZER, or PATTERN_ANALYZER.) - Add unit tests (`bigquery/search/bigquery_search_with_text_analyzer_test.py`) covering both the success path and API error handling (`GoogleAPICallError`) --- .../bigquery_search_with_text_analyzer.py | 82 +++++++++++++++++++ ...bigquery_search_with_text_analyzer_test.py | 67 +++++++++++++++ bigquery/search/noxfile_config.py | 23 ++++++ bigquery/search/requirements-test.txt | 1 + bigquery/search/requirements.txt | 1 + 5 files changed, 174 insertions(+) create mode 100644 bigquery/search/bigquery_search_with_text_analyzer.py create mode 100644 bigquery/search/bigquery_search_with_text_analyzer_test.py create mode 100644 bigquery/search/noxfile_config.py create mode 100644 bigquery/search/requirements-test.txt create mode 100644 bigquery/search/requirements.txt diff --git a/bigquery/search/bigquery_search_with_text_analyzer.py b/bigquery/search/bigquery_search_with_text_analyzer.py new file mode 100644 index 00000000000..686522ff7e7 --- /dev/null +++ b/bigquery/search/bigquery_search_with_text_analyzer.py @@ -0,0 +1,82 @@ +# Copyright 2026 Google LLC +# +# Licensed under the Apache License, Version 2.0 (the "License");
