Query parameters

http://dlexdb.de/sr/dlexdb_wl/kern/lem/filter/?order_prop=PROP&order_dir=DIR&$top=TOP

All query parameters are optional.

order_prop

Name of the property (database column) to use for the ordering of the result set. Ordering by more than one column is not supported.

order_dir

desc or asc

top

Maximum number of results to be retrieved. If no limit is given, a maximum number of 10 results will be delivered by default.

Filter expression

The POST body may be empty, or it may contain a filter expression according to the syntax below. Its content type should be given as Content-type: text/query-dlexdb. This content type is plain text in UTF-8 encoding, and the contents must follow the following format:

    PROP1__OP1=VAL1
    PROP2__OP2=VAL2
    ...

where PROPn is the name of a property (database column), OPn is an operator, and VALn is a value of the appropriate type. PROPn and OPn are separated by two underscores, and there are no spaces around the = sign. String values must not be quoted, but may contain spaces. Surrounding whitespace and empty lines will be ignored by the parser.

Operators are:

eq	equals (for numbers or strings, case-sensitive)
eqi	equals (for strings, case-insensitive)
re	regular expression match (for strings, case-sensitive)
rei	regular expression match (for strings, case-insensitive)
ge	greater or equal (for numbers)
le	less or equal (for numbers)

Multiple conditions on the same field using the same operator are not allowed. One of them would be chosen randomly while the others are discarded.
