Hi,
Making this thread to ask for advice on how to best handle the following situation in Foxtrot. Please pardon me if this has been covered elsewhere.
Suppose I have files (.pdf, .docx) pertaining to a subject, say, "Linear Algebra", and they are are located at TWO distinct directory paths. My goal is to make all of these files searchable in Foxtrot, preferably under a single index.
The first location is easy to add to a Foxtrot index because all documents are housed in the same directory path, for example:
/path/to/lin_alg/lecture1.pdf
/path/to/lin_alg/lecture2.pdf
/path/to/lin_alg/lecture3.pdf
/path/to/lin_alg/tutorial1.pdf
(Currently, I am only indexing this first location. It would be nice if the relevant files in the second location, which I share about next, could be added to this index)
The second location is more challenging. The relevant documents are housed in separate child paths. Additionally, there are documents UNrelated to "Linear Algebra" in neighboring paths. To illustrate what I mean, the paths look something like these:
/path/to/bookshelf/Kevin-H/linear_algebra_book1.pdf
/path/to/bookshelf/Sheldon-A/linear_algebra_book2.pdf
/path/to/bookshelf/Sergei-W/linear_algebra_book3.pdf
/path/to/bookshelf/John-B/self_love_book.pdf
/path/to/bookshelf/Vivian-K/cooking_western_cuisine_book.pdf
/path/to/bookshelf/Eugene-P/probability_theory_book.pdf
[… so on and so forth …]
To clarify, the last three documents (self_love_book.pdf, cooking_western_cuisine_book.pdf, probability_theory_book.pdf) are not related to the subject "Linear Algebra", and as such, should be excluded from indexing.
If anyone is curious as to the complicated structuring of the second location, the reason is that it is automatically generated by the open-source digital book management app called "Calibre", which I'd like to think is quite widely used to manage digital books.
If you're reading this, I'd be happy to hear your opinions or advice if you have any you'd like to share.
At the moment I'm thinking whether it'd be possible for me to tag the books in the second location with the tag "Linear Algebra", and then tell Foxtrot to only index these tagged files in this particular location while ignoring other files. I'm currently on Mac OS so I'm guessing tagging should be done with Mac OS's native file tags. I think what Mac OS does when tagging a file is to add an extended attribute to it; and I'm hoping that Foxtrot allows filtering such attributes when specifying which files to include in an index.
If anyone knows of a better solution, please feel free to share, I would be very thankful to hear it.
Well, it appears that my post has turned out kind of lengthy, so thank you for reading through all this.

You can only index whole folders, skipping some subfolders (at any depth) you manually add to the relevant pane.
You can't skip from indexing files or folders based on their tag, but you can use tags at search time (this applies to files tagged individually; you can't tag a folder to mark all the files its contains):
- use the "by Tag" categorizer in the left pane to filter the found files
- or add a [tags] criterion
- or add a [then apply advanced filter] [tags] criterion

I'll share how I manage my searches in these situations, and maybe some of it useful for your situation. In all situations below, I create only 1 index for all the file locations, and I don't split up indexes.
Situation 1
If the files you're searching for contain the same pattern of keywords in their filenames or pathnames, then search for "full path" using regular expressions. Specifically, use "Then apply advanced filter" -> "Full Path" -> "Contains any of the regular expression". For example, if all the files contain "lin alg" or "linear algebra" in their filename or pathname, then you can write a regular expression to search for both variants.
Situation 2
If the files you're searching for is part of list, but their filenames don't necessarily have anything in common, then you probably have to use a more involved process. For me, I would write a script to grab the first 20 characters from the filename of each file (or their unique fileID if they have one), and then concatenate them together in a procedural manner to automatically generate a long search string with a bunch of "OR". For example, search for filenames with with "string1 OR string2 OR string3 ..etc.". Use this with the feature Foxtrot feature "Contains any of the strings". <-- This is probably not you, but I'm just highlighting the option.
Situation 3
If you use tags, then you should just use the method suggested by Foxtrot Engineering. Tags offer a painless way to deal with situations like this. However, I avoid using tags because (1) tag data doesn't travel well (2) I can't easily back up tag data structure (3) tag data can only be read within Mac ecosystem. I do use tags for data processing purposes, such as tagging a large group of files with temporary tags for data processing, and then deleting the tag data afterward.

Quote:However, there is a hidden preference (configurable from Terminal.app) to exclude files or entire folders based on their name or path.
This prompted me to lookup the new feature in Foxtrot 8. Please confirm if my understanding is correct: Users can now choose which file/folder to index by applying regular expression filter on the full path? For example, I can choose to index only files with {regex pattern A} or NOT index files with {regex pattern B}? Why is this not news??? This makes Foxtrot indexes so much easier to use. Currently, I've been applying fullpath regex on every new search just because I cannot perform the regex filter at index-time.
Quoted from documentation:
"With version 8, you can also define custom regular expressions to specify some other files or folders to skip. You can either use a single regular expression (define SkipPathRegex as a string) or multiple ones (define SkipPathRegex as an array of strings). To avoid incorrect parsing when using the defaults command, it is suggested to quote the regular expression between single quotes ('), and to prepend any string with a "-string" argument. The regular expression is applied to the full path, and a file or folder is skipped if its path contains the regex; use a leading ^ and / or a trailing $ if the regex should be found at the beginning / ending of the path."
As a small comment, I can see why you might not want to apply regex at index-time, and instead encourage user to apply regex only at search-time, because you might be slowing down the index update process. Currently, my index update process is already taking 8 - 10 seconds, and I wouldn't want the update process to approach 15 - 20 seconds. Nonetheless, it's a good option to give users. So kudos, if this feature is actually implemented.

- this is a global setting that applies to all your indices. The goal is more to exclude some kind of configuration, cache, log, dump or archive files, rather than to have complex rules to organize documents with a path nomenclature
- the regexes are used to exclude some files or folders; if you only want to index files that match a given regex, you will have to write the opposite regex to exclude the other files, which can be quite tricky

This is true, in case anyone ever wants to write complex regex that negate conditions. Thanks for clarifying that the feature is designed mainly to perform global exclusion from indexes.

Trying my luck here:
Suppose a pdf file's tags – say, tags being "cooking" and "fusion cuisine" for a cookbook – could be written to the pdf file's XMP headers under the key "kMDItemKeywords", could this data still be filtered on in Foxtrot Pro? Noticed that Mac OS tags are written to a different key – "kMDItemUserTags".
In case anyone is curious why this is happening, it's because the ebook management app I use embeds its tags under "kMDItemKeywords".

Yes, PDF keywords can also be used; they are handled by FoxTrot as part of "keywords and comments". There is no categorizer for this in the left pane, but you can add a second search criterion for [keywords and comments].
If you specifically want to search kMDItemKeywords but not other metadata that FoxTrot handles in the same "keywords and comments" field (like kMDItemProjects, kMDItemComment or kMDItemMusicalGenre), then you need to add a [then filter by Spotlight attribute] criterion; see this other topic
