如何在couchbase中搜索数字全尺寸日语

Question

我在couchbase 6.0.3中尝试全文搜索全尺寸“9”时出现错误。异常抛出: err: bleve: QueryBleve验证请求，err: parse错误:错误分析编号: strconv.ParseFloat: parsing。

如果我使用某个字符串“9abc”进行搜索，那么我认为搜索成功了，couchbase搜索regconize“9”的lib是number，解析失败。我不知道该怎么解决问题。请帮帮我!

Couchbase 6.0.3

ConjunctionQuery fts = SearchQuery.conjuncts(SearchQuery.queryString(source));
fts = fts.and(SearchQuery.matchPhrase("123").field("tm"));
fts = fts.and(SearchQuery.booleanField(true).field("active"));

SearchQuery query = new SearchQuery("segmentIndex"), fts);
SearchQueryResult result = bucket.query(query);

异常抛出: err: bleve: QueryBleve验证请求，err: parse错误:错误分析编号: strconv.ParseFloat: parsing。

您可以尝试自定义分析器与asciifolding字符过滤器，如下所示。

此外，当你直接从没有字段名的UI框中进行搜索时，它会在"_all“字段中进行搜索，这将不会得到正确的/预期的分析器来解析查询文本。

您可以将查询的字段作用域设置为类似于=>字段：“9”

Asciifolding过滤器是6.5.0 Couchbase版本的一部分。它有测试版可供试用。
