#### `i3.add_search_filter(name, function(item, values))`
Adds a search filter with the given `name`.
Adds a search filter with the given `name`. `values` is a table of all possible values.
The search function must return a boolean value (whether the given item should be listed or not).
Example function sorting items by drawtype:
```lua
i3.add_search_filter("type", function(item, drawtype)
if drawtype == "node" then
return reg_nodes[item]
elseif drawtype == "item" then
return reg_craftitems[item]
elseif drawtype == "tool" then
return reg_tools[item]
i3.add_search_filter("types", function(item, drawtypes)
local t = {}
for i, dt in ipairs(drawtypes) do
t[i] = (dt == "node" and reg_nodes[item] and 1) or
(dt == "item" and reg_craftitems[item] and 1) or
(dt == "tool" and reg_tools[item] and 1) or nil
end
return #t > 0
end)
