Azure搜索是否存储可搜索字段的术语频率? [英] Does Azure Search store term frequencies for searchable fields?

问题描述

我了解可搜索字段的Azure搜索索引会为每个分析的术语创建一个反向索引，但是无法在文档中找到是否存储了每个术语的术语频率.

I understand that an Azure Search index for a searchable field creates an inverted index for each analyzed term, but cannot find within the documentation whether or not the term frequency for each term is stored.

Azure搜索是否将术语可搜索字段的频率存储在某个地方?似乎只需要计算一次即可为每个搜索查询计算效率.

Does Azure Search store the term frequencies for searchable fields somewhere? It seems as if it would be inefficient to calculate it for every search query when it would only need be computed once.

如果是这样，是否有可能为单独的处理步骤提取/下载整个数据集的术语频率?

If so, is it possible to extract/download the term frequencies for the entire data set for separate processing steps?

推荐答案

我们确实维护术语频率以快速计算TF/IDF之类的东西.不幸的是，目前尚无法从Azure搜索中获得该信息.

We do maintain term frequencies to compute things like TF/IDF quickly. Unfortunately there's no way currently to get that from Azure Search though.
