Info

dictionary: (required) The path of a file that contains a list of simple words, one per line. Blank lines and lines that begin with "#" are ignored. This path may be an absolute path, or path relative to the Solr config directory. minWordSize: (integer, default 5) Any token shorter than this is not decompounded. minSubwordSize: (integer, default 2) Subwords shorter than this are not emitted as tokens. maxSubwordSize: (integer, default 15) Subwords longer than this are not emitted as tokens. onlyLongestMatch: (true/false) If true (the default), only the longest matching subwords will generate new tokens. Example: Assume that germanwords.txt contains at least the following words: dumm kopf donau dampf schiff In: "Donaudampfschiff dummkopf" Tokenizer to Filter: "Donaudampfschiff"(1), "dummkopf"(2), Out: "Donaudampfschiff"(1), "Donau"(1), "dampf"(1), "schiff"(1), "dummkopf"(2), "dumm"(2), "kopf"(2) Unicode Collation Unicode Collation is a language-sensitive method of sorting text that can also be used for advanced search purposes. Unicode Collation in Solr is fast, because all the work is done at index time. Rather than specifying an analyzer within , the solr.Colla tionField and solr.ICUCollationField field type classes provide this functionality. solr.ICUCollatio nField, which is backed by the ICU4J library, provides more flexible configuration, has more locales, is significantly faster, and requires less memory and less index space, since its keys are smaller than those produced by the JDK implementation that backs solr.CollationField. solr.ICUCollationField is included in the Solr analysis-extras contrib - see solr/contrib/analys is-extras/README.txt for instructions on which jars you need to add to your SOLR_HOME/lib in order to use it. solr.ICUCollationField and solr.CollationField fields can be created in two ways: Based upon a system collator associated with a Locale. Based upon a tailored RuleBasedCollator ruleset. Arguments for solr.ICUCollationField , specified as attributes within the element: Using a System collator: locale: (required) RFC 3066 locale ID. See the ICU locale explorer for a list of supported locales. strength: Valid values are primary, secondary, tertiary, quaternary, or identical. See Comparison Levels in ICU Collation Concepts for more information. decomposition: Valid values are or . See for more no canonical Normalization in ICU Collation Concepts information. Apache Solr Reference Guide 6.0 148
Using a Tailored ruleset: custom: (required) Path to a UTF-8 text file containing rules supported by the ICU RuleBasedCollator strength: Valid values are primary, secondary, tertiary, quaternary, or identical. See Comparison Levels in ICU Collation Concepts for more information. decomposition: Valid values are no or canonical. See Normalization in ICU Collation Concepts for more information. Expert options: alternate: Valid values are shifted or non-ignorable. Can be used to ignore punctuation/whitespace. caseLevel: (true/false) If true, in combination with strength="primary" , accents are ignored but case is taken into account. The default is false. See CaseLevel in ICU Collation Concepts for more information. caseFirst: Valid values are lower or upper. Useful to control which is sorted first when case is not ignored. numeric: (true/false) If true, digits are sorted according to numeric value, e.g. foobar-9 sorts before foobar-10. The default is false. variableTop: Single character or contraction. Controls what is variable for alternate Sorting Text for a Specific Language In this example, text is sorted according to the default German rules provided by ICU4J. Locales are typically defined as a combination of language and country, but you can specify just the language if you want. For example, if you specify "de" as the language, you will get sorting that works well for the German language. If you specify "de" as the language and "CH" as the country, you will get German sorting specifically tailored for Switzerland. ... ... In the example above, we defined the strength as "primary". The strength of the collation determines how strict the sort order will be, but it also depends upon the language. For example, in English, "primary" strength ignores differences in case and accents.
