setQueryCompilers

public void setQueryCompilers(java.util.Collection<? extends io.georocket.query.QueryCompiler> queryCompilers)

Constructs the compiler

Parameters:

queryCompilers - query compilers for individual properties

compileQuery

public io.vertx.core.json.JsonObject compileQuery(java.lang.String search,
                                                  java.lang.String path,
                                                  java.lang.String keyExists)

Compile a search string

Parameters:

search - the search string to compile

path - the path where to perform the search (may be null if the whole data store should be searched)

keyExists - the name of a property which must exist in the document

Returns:

the compiled query

compileQuery

public io.vertx.core.json.JsonObject compileQuery(java.lang.String search,
                                                  java.lang.String path)

Compile a search string

Parameters:

search - the search string to compile

path - the path where to perform the search (may be null if the whole data store should be searched)

Returns:

the compiled query
