What I mean is that we can't reuse the matching rules in radixtree.lua,
because his definition is local.
The matching rule definition in radixtree.lua:
```lua
local compare_funcs = {
["=="] = function (l_v, r_v)
if type(r_v) == "number" then
l_v = tonumber(l_v)
if not l_v then
return false
end
end
return l_v == r_v
end,
["~="] = function (l_v, r_v)
return l_v ~= r_v
end,
[">"] = function (l_v, r_v)
l_v = tonumber(l_v)
r_v = tonumber(r_v)
if not l_v or not r_v then
return false
end
return l_v > r_v
end,
["<"] = function (l_v, r_v)
l_v = tonumber(l_v)
r_v = tonumber(r_v)
if not l_v or not r_v then
return false
end
return l_v < r_v
end,
["~~"] = function (l_v, r_v)
local from = re_find(l_v, r_v, "jo")
if from then
return true
end
return false
end,
["IN"] = in_array,
["in"] = in_array,
}
```
