addAnd

protected AndItem addAnd(Item item,
                         AndItem and)

protected Item combineItems(Item topLevelItem,
                            Item item)

Returns the top level item resulting from combining the given top level item and the new item. This implements most of the weird transformation rules of the parser.

handleComposite

protected Item handleComposite(boolean topLevel)

anyItems

protected Item anyItems(boolean topLevel)

A collection of one or more items. More items are collected in the default composite - or. If there's a explicit composite and some other terms, a rank terms combines them

positiveItem

protected Item positiveItem()

protected Item compositeItem()

setSubmodeFromIndex

protected void setSubmodeFromIndex(java.lang.String indexName,
                                   IndexFacts.Session indexFacts)

Sets the submodes used for url parsing. Override this to influence when such submodes are used.

indexableItem

protected Item indexableItem()
