Field Detail

SPELLCHECK_PREFIX

static final String SPELLCHECK_PREFIX

Constant Field Values

SPELLCHECK_DICT

static final String SPELLCHECK_DICT

The name of the dictionary to be used for giving the suggestion for a request. The value for this parameter is configured in solrconfig.xml

See Also:

Constant Field Values

SPELLCHECK_COUNT

static final String SPELLCHECK_COUNT

The count of suggestions needed for a given query.

If this parameter is absent in the request then only one suggestion is returned. If it is more than one then a maximum of given suggestions are returned for each token in the query.

Constant Field Values

SPELLCHECK_ONLY_MORE_POPULAR

static final String SPELLCHECK_ONLY_MORE_POPULAR

When this parameter is set to true and the misspelled word exists in the user field, only words that occur more frequently in the Solr field than the one given will be returned. The default value is false.

This is applicable only for dictionaries built from Solr fields.

Constant Field Values

SPELLCHECK_EXTENDED_RESULTS

static final String SPELLCHECK_EXTENDED_RESULTS

Whether to use the extended response format, which is more complicated but richer. Returns the document frequency for each suggestion and returns one suggestion block for each term in the query string. Default is false.

This is applicable only for dictionaries built from Solr fields.

Constant Field Values

SPELLCHECK_Q

static final String SPELLCHECK_Q

Use the value for this parameter as the query to spell check.

This parameter is optional. If absent, then the q parameter is used.

Constant Field Values

SPELLCHECK_BUILD

static final String SPELLCHECK_BUILD

Whether to build the index or not. Optional and false by default.

See Also:

Constant Field Values

SPELLCHECK_RELOAD

static final String SPELLCHECK_RELOAD

Whether to reload the index. Optional and false by default.

See Also:

Constant Field Values

SPELLCHECK_COLLATE

static final String SPELLCHECK_COLLATE

Take the top suggestion for each token and create a new query from it

See Also:

Constant Field Values

SPELLCHECK_MAX_COLLATIONS

static final String SPELLCHECK_MAX_COLLATIONS

The maximum number of collations to return. Default=1. Ignored if "spellcheck.collate" is false.

See Also:

Constant Field Values

SPELLCHECK_MAX_COLLATION_TRIES

static final String SPELLCHECK_MAX_COLLATION_TRIES

The maximum number of collations to test by querying against the index. When testing, the collation is substituted for the original query's "q" param. Any "qf"s are retained. If this is set to zero, does not test for hits before returning collations (returned collations may result in zero hits). Default=0. Ignored of "spellcheck.collate" is false.

Constant Field Values

SPELLCHECK_MAX_COLLATION_EVALUATIONS

static final String SPELLCHECK_MAX_COLLATION_EVALUATIONS

The maximum number of word correction combinations to rank and evaluate prior to deciding which collation candidates to test against the index. This is a performance safety-net in cases a user enters a query with many misspelled words. The default is 10,000 combinations.

Constant Field Values

SPELLCHECK_COLLATE_EXTENDED_RESULTS

static final String SPELLCHECK_COLLATE_EXTENDED_RESULTS

Whether to use the Extended Results Format for collations. Includes "before>after" pairs to easily allow clients to generate messages like "no results for PORK. did you mean POLK?" Also indicates the # of hits each collation will return on re-query. Default=false, which retains 1.4-compatible output.

SPELLCHECK_ACCURACY

static final String SPELLCHECK_ACCURACY

Certain spelling implementations may allow for an accuracy setting.
