Syntax:

[:CLASS ][!]ARG1 [!]ARG2
or
[:CLASS ][!]ARG1.ARG2

Where CLASS is:

 c - const
 v - var
 m - method
 t - type
 f - func

Default CLASS is:

 tcfv (type/const/func/var)

Exclamation mark ('!') means "show the best match only". In the second syntax
form, exclamation mark is applied to both arguments.

ARG1 is used as a pattern to search for an entity of a certain class, which
matches that pattern:

 c - search for a named const group, then for a const inside unnamed group and
     then for an individual const entity

 v - search for a var group, then for a var inside unnamed group and then for
     an individual var entity

 m - search for methods of type that matches ARG1 (for this class, '!'
     modificator is implicitly enabled, e.g. search request only shows all
     methods of the best matched type)

 t - search for a type

 f - search for a func

ARG2 is used as a pattern to filter 'm' (method) search results only.

Examples:

--------------------------------------------------------------
`:tm !Rectangle` - Search for a type and methods of that type, show only the best
match (note that '!' is implicit for 'm', but not for 't')

--------------------------------------------------------------
`:tcfv Expr` or `Expr` - Search for a type/const/func/var that matches 'Expr'
pattern, multiple results are displayed that way:

t, c, f, v, t, c, v, f, t, c, f, v, t, c, f, v, ...

It there is one type, two consts and four funcs, the output will be:

t, c, f, c, f, f, f

--------------------------------------------------------------
`:fc !Magic` - Search for the best matched func and const using pattern 'Magic'.

--------------------------------------------------------------
`!vspec` - Search for the best matched type/const/func/var using pattern
'vspec', for example in "go/ast" package it will show ValueSpec type.
