[tw5] Re: Search the values of fields where field names are generated?
Yes Eric that is exactly what I meant. It's basically a location search
for common gedcom tags (which are not the same as TiddlyWiki tags.)
Thanks so much for the examples.
I have been reading about macros but I still don't think I grasp them fully
yet. However, though experimentation I have come up with the following 2
examples which give me better control over the title lists. The first works
fine. I prefer the 2nd example as it's more general. I think it can
generalize even more into a macro named "location-search" maybe. Something
similar to <>
First Example:
\define searchflds()
<$list filter="[search:$(flds)$[California]]">
\end
<$vars flds={{{ [fields[]regexp[_plac$]join[,]] }}}>
<>
Second Example:
\define search-filter(term) [search:$(flds)$[$term$]]
<$vars flds={{{ [fields[]regexp[_plac$]join[,]] }}}>
<$list filter=<> >
<$link>{{!!caption}} {{||year-span}}

Addendum:
The above code will work, but... it searches for each field name
separately. As a result, if there are multiple fieldnames in the same
tiddler that contain the query text, that tiddler will be listed multiple
times.
Your intuition to use "join[,]" to construct a list of fields is actually
the better approach. Thus:
<$vars flds={{{ [fields[]regexp[_plac$]join[,]] }}}>
<>
Notes:
* the $vars finds all fieldnames ending in "_plac" and assembles a
comma-separated list
* the searchflds macro then uses that list of fieldnames to find the
occurrences of "query" within any of those fields
Because the search is looking in all of the "_plac" fieldnames at the same
time, any matching tiddlers are only listed once.

If I understand your goal correctly, you want to find all tiddlers that
have a fieldname ending in "_plac" and then search those fields for a value
that contains the text "query" and then show the names of those tiddlers
If that is the case, then you were very close. The issue is that filter
syntax doesn't permit use of variables in the suffix (e.g. the part after
the colon in "search:suffix").
However, you can work around this by using a macro to substitute the
variable value into the syntax, like this:
\define searchflds() {{{ [search:$(flds)$[query]] }}}
<$list filter="[fields[]regexp[_plac$]]" variable="flds">
<>

Here's is the actual filter. I thought maybe the join is more correct with
the search operator:

Is possible?

I thought to reverse it also - that is search all fields for the term and
then filter the titles by the selected fields, but I didn't have any luck
with that filter syntax. It's possible I just haven't typed the filters
correctly.

It is true I am still having difficulty with the appropriate contexts and
meanings of the various types and amounts of brackets.
But alas, it did not work.

It will probably work if you just change <> to inside the
internal filter. Inside of filters, variables use single angle brackets.
Outside filters, double angle brackets.
