Class Summary

Class	Description
AlphanumBWPattern	Alphanumerical value to query in the index or to highlight.
AlphanumValue	Alphanumerical value to query in the index or to highlight.
And	Boolean operator for a logical conjunction of branches. It results from an AND in Exalead Query Language. Is is possible to either sum the scores of the branches or to take the maximum. By default the scores are summed.
Around
AssemblyShapeVolumeNode
At	This unary operator denotes an Autocache query branch

AttrGraphFields
AttrGraphTraverse	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
AttributeFilter	Query to filter results from a graph query by applying the V6 attribute filtering algorithm.
AttrSimilar
AttrSimilarBin
Autocache	This unary operator denotes an Autocache query branch
BatchOr	Boolean operator for a logical disjunction of branches. It results from an OR in Exalead Query Language. Is is possible to either sum the scores of the branches or to take the maximum.
BoxVolumeNode
ButNot	Implement the ButNot word-level expression. This node is used to match docs that match a boolean expression, but that do not match a more specific word-level expression. Example: "new BUTNOT (new york)" will match documents which contain new but not the sequence "new york"
CategoryValue	Match a category path in a given category field
Chemical	Implement the CHEMICAL operator. Please refer to the documentation for details on the CHEMICAL operator.
ConsecutiveQueries	Perform several queries consecutively in the index.
CutPath	Cuts paths from a graph representation.
DidListNode	Matches given dids if they are in the support.
Distance
ELLQLString	An unparsed ELLQL string
ErrorNode
FalseNode	Boolean FALSE.
FindGraphRoots	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
FindInContext	Used to apply security on graph expressions.
FindPath	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
FuzzyAnd	Boolean operator for a logical conjunction of branches. It results from a FUZZYAND in Exalead Query Language. Is is possible to either sum the scores of the branches or to take the maximum. By default the scores are summed.
If	This unary operator denotes an Autocache query branch
IndexOptions	Node-specific options for the processing of the node by the index.
IndexValue	A leaf node that the index can directly evaluate
InnerJoin	Implement the INNERJOIN operator. Please refer to the documentation for details on the INNERJOIN operator.
NamedQueryNode	This node must be substituted with a partial AST.
NaryNode	A query node that contains several other ones
Near	Orderless proximity matching. This node matches if all words are found within a sliding window of size "distance" words.
Node	Base interface for all nodes of the query tree
NodeVisitor	Base class for all visitors along the Query tree. You can define your own visitor by only overriding the required methods.
None
NoOp	Temporary terminal No-op node. This node can be used for internal usage, to temporarily indicate that there is nothing here.
Not	Boolean negation
NoVolumeNode
NumericalValue	A numerical value to query in a field. Numerical matching can be done either through inverted lists (without bitrange specification) or through attributes (with bitrange specification).
Opt	This unary operator denotes an Optional query branch (pure ranking term). It results from an OPT in the Exalead Query Language.
Or	Boolean operator for a logical disjunction of branches. It results from an OR in Exalead Query Language. Is is possible to either sum the scores of the branches or to take the maximum.
PathIntersection	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
PathMinus	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
PathNode	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
PathUnion	Query using a graph representation: it returns objects that match the first query, its child match the second, its second child the third, etc.
PrefixNode	The content of this is contained in a "prefix".
ProgressiveExpandQuery
RangeNode	The content of this is contained in a "prefix".
RayVolumeNode
RemovedNode	Pseudo-node for stop words and their single-token expansions.
ReservedWord	A reserved word from user query.
RootNode	The root of the boolean matching tree
SecuredGraph	Used to apply security on graph expressions.
Separator	Separator match
Sequence	Strict ordering proximity matching. This node matches if all words are in the requested order and within "distance" of each other. You may also provide one [min:max] distance per pair of consecutive children, in which case there must be numChildren-1 distances.
Sequence.MinMaxPair	A simple structure to store a min and max distance
SequenceFilter	Query to filter results from a graph query by applying a sequence of criteria
ShapeDiagVolumeNode
ShapeVolumeNode
SphereVolumeNode
Split	Implement the Split word-level expression. This node is used to match docs that match a word-level expression within a chunk defined by a separator expression. Example: #split(#sequence(a b), c) will match "d e c x a b c e" but not "c a c b"
Subpaths	Query using a graph representation: it returns objects that match the second query, and are prefixed by the results of the firs query
TextNode	Base class for "semantic" nodes
TextNode.TextProcessingOptions	Options for the text processing of one query node.
TokenizedNode	A chunk of tokenized text with forms.
TokenizedNode.Form	A "form" for the query of a part of a TokenizedNode. A form spans a given number of tokens from the TokenizedNode, and is made of several other tokens.
TokenizedNode.Token	A token, either from the query or from one of the forms
TrueNode	Boolean TRUE, always matches
TypeFilter	Used to apply type filtering on graph query results.
UidListNode	Matches given uids.
UnaryNode	A query node that contains another one
UserQueryChunk	A chunk of text, considered to be without operators This chunk is not yet tokenized and not directly usable for index query.
UserQueryElement	A parsed element from the user query, either regular chunk or regexp
UserQueryRegexp	A regexp from user query.
UserQueryString	An unparsed (with operators) user query string. The whole user query should go in a single UserQueryString under the Root node.
