Answer to question #1: By default, titles resulting from a filter are only listed once, with the last instance of a given title "dominantly appended" to the list (i.e., duplicates are removed). Thus, in your example, adding `[[foo]]` to the end of the list automatically removed the first instance of `foo` from the front of the list. You've already discovered the use of the `:raw` suffix for the `enlist-input` operator, which prevents duplicates from being removed when you enlist an existing space-separated list. Another bit of filter syntax that helps with preserving duplicates is the "=" prefix on a filter run. To get the results you expected, you would write: `[[foo foo foo bar]enlist-input:raw[]] =[[foo]]`.
Answer to question #2: As you noted in your followup message, you have an existing list stored in a tiddler field called `fieldName`. Let's assume this field contains 4 items: `foo [[bar baz]] mumble [[frotz gronk snork]]` (where the 2nd and 4th items contain spaces). To add an item to that list, you would write something like this:: `[<currentTiddler>get[fieldName]enlist-input:raw[]] =[<addedTitle>]`. Note also that using `<currentTiddler>` in your filter is *slightly* more efficient than `all[current]`, since the `all[]` operator first needs to parse the operand (`current`) to determine that you want to retrieve the current tiddler's title, while `<currentTiddler>` directly retrieves the title without the added internal layer of parsing. enjoy, -e On Wednesday, February 16, 2022 at 2:17:51 PM UTC-8 [email protected] wrote: > Ok, so I have the following list: > > foo foo foo bar > > I then want to append 'foo' to the end of that list such that I wind up > with: > > foo foo foo bar foo > > So I try the following filter: > > [[foo foo foo bar]enlist-input:raw[]] [[foo]] > > That results in: > > foo foo bar foo > > This is unexpected to me, which means that there is something I don't > understand. > > So I have two questions: > > 1.
