MS SharePoint 搜索 API 没有返回所有文件

Question

I'm using the MS SharePoint Search API over Rest to get the file paths to all PDF files on a SharePoint site. I use the Search API iterative, because there are more than 5000 file on the site.

What I'm doing is:

https://[root_url]/_api/search/query?QueryText='*+site:"[root_url]/[listname]"'
&RowLimit=500&RowsPerPage=500&StartRow=0&Refiners='fileType'
&RefinementFilters='fileType:pdf'&TrimDuplicates=false

...until the list is empty.

The listname contain a whitespace.The query works, it returns 2661 files. TrimDuplicates does its job somehow. Without TrimDuplicates, the query returns only 1169 files.

Some of the missing files are duplicates. They are at different places with the same name and content. But some files are missing at all.

I can download the missing files via:

https://[root_url]/_api/web/GetFolderByServerRelativeUrl('[path]')/Files('[filename]')/$value

Any hints?

You could use the search query tool to query the missing document (eg by title or path) and compare the managed properties with your filters in the query. If you cannot get the file via search query at all, please ensure that the list is not excluded from search index and a crawl indexed the document.
