Not organized or listed in a systematic way, making it difficult to find or access information.
The documents were unindexed, so it took a long time to locate the specific file.
Unindexed → It is formed from "un-" (meaning not) and "index" (from Latin "index", meaning a pointer or list). The word "unindexed" means not having an index or not being listed in an index.
Think of 'not' ('un-') having a 'pointer' or 'list' ('index') — that's why unindexed means something that does not have a list or pointer.
