Yes I recall the discussions and I recall thinking --- hmmm, I've not noticed any change, maybe that's because I have the author and title related settings at the factory defaults. However my backup logs reveal that thousands of my library folders and format files haven't been synched for a year or more.

But this probably because I avoid using long names in the first instance, if there's going to be any shortening of folder or file names I prefer to apply my domain knowledge to do it, rather than leave it to a mechanistic algorithm.

When I add a book the first thing I do is to get the author names and title 'right', in doing that I look at the names of the folders and files created, if necessary I make changes so that the folder and file names are 'sensible'.

The OP already covered that point, in post #5 MelBr wrote the following

But the gist of your post does go to the nub of MelBR's issue.

Calibre's 'search facility' is primarily based on querying its heavily indexed relational database, which contains structured data. I know there are Comments and similar columns - but inclusion of them in a calibre search can have a dramatic deleterious impact on search times - as in minutes rather than a couple of seconds.

However MelBR compares calibre to facilities found on search sites such as Google and sites that use Lucene. But I suspect MelBR knows full well that the techniques used to index structured data in a relational database (and a small single user one at that), and those used to index unstructured data on a zillion web pages and documents are not quite the same thing.

And that's why in the context of calibre I interpret the word 'search' as 'query' - because that's what it does, it interrogates a relational database using Structured Query Language.

Its also why I will continue to use my OS for my real searches, I almost always want to search beyond my calibre libraries, I want to see emails, letters, receipts, invoices, blog posts, media transcripts etc, etc. I don't expect calibre to find those things any more than I expect Quod Libet (music library) to find pictures of my cat.
