Compose filters without the presence of a collection?

it fixes the issue I believe you'd have to add a reference to the original filter to avoid a recursive call.
code :
var previousFilter = filter;
filter = c => previousFilter(c) && c <= 10;

around this issue I would like to pass a collection through series of non-collection functions. It could be achieved by using map multiple times. How to do it more concisely and clojure/functional programming idiomatic way: , That should work: (map (comp to-int sanitize get-text) coll)

fixed the issue. Will look into that further You failed to mention if the library needs to be free/open source or if commercial libraries are acceptable but one of the best out there is GdPicture.NET. I doubt you'll find anything free that is remotely comprehensive but a good free one is Filters library (LGPL).

this will help How about you publish the entire collection with just the filter fields, using field specifiers? That way it's just like an extra collection with just the filters, and in the results you can choose to only display documents that don't just have a tag field.
However a better idea, in my opinion, is to do something similar to mohamed's suggestion, and normalize things a bit. Have a separate Tags collection that contains a tag name and id, and have a TagsUsers connection that stores the tag id and user id. That will make filtering much easier, because then you can simply publish the tags collection to the client, add/delete/edit tags only once, and easily filter the publish method on the server.
