This problem occurs due to the browser sending the wrong MIME type during a file upload. It appears that Windows boxes where MS Excel handles CSV files uploads CSV files with the "application/vnd.ms-excel" MIME type. It can cause the search index to be only partially built, resulting in missing pages in search results.

Workaround
Stop Confluence, edit the confluence/WEB-INF/classes/mime.types file and add the following entry:
text/csv csv
This ensures that all files with the CSV extension are mapped to the text/csv MIME type regardless of what the browser sends.
Next, run the following query against the database and then start Confluence:
update attachments set contenttype='text/csv' where lower(title) like '%.csv';
To make the content in the CSV files searchable you will also need to run a reindex.
