The list of search results is limited to 500 in most cases. If you are performing a search that would return more than 500 results, try using additional parameters to narrow your search and find the document(s) that you need.

If the search entered takes more than 30 seconds, the search will timeout and an error will be returned. This can happen when searching very large sets of documents with broad parameters. One likely cause of this would be using the "contains" parameter when limiting your search, e.g. The "UDDS" field contains "064". Such a search cannot use search indexing and thus will take longer and be more likely to timeout.
