Such fields cannot be used as suggestions. Both their names and values are copied directly without any modification. The copyAsIsFields attribute defines a list of comma-separated field names that should be copied to AC as is.
#Solr typeahead update#
You can do that by making use of the included bin/prep-classpath.sh script:Įach document added to main solr core for indexing will be processed by custom AC update request processor and values of fields specified in the “fields" parameter will be extracted, processed, and added to AC as suggestions. To satisfy their run-time dependencies, make sure the CLASSPATH is set correctly. Because IndexLoader reads directly from the local Lucene index given a path to index directory, this IndexLoader should either be used when the index is not sharded or it should be run against all index shards. To feed AC back-end with data, use one of the two command-line loaders:Īs their names imply, FileLoader gets data to push into AC back-end from a file, while IndexLoader gets data from the index. Optionally adjust the names of fields in schema.xml (describer later in the document)Īt this point the AC back-end should be running, but will be empty and thus have no data to suggest.Copy solrconfig.xml and schema.xml to the Solr $SOLR_HOME/server/solr/collection1/conf/ directory.
#Solr typeahead install#
To install AC into solr place the following libraries from the package into your $SOLR_HOME/server/solr-webapp/webapp/WEB-INF/lib/ directory:ĭeployment to an existing, but fresh non-multi-core Solr: Installing AC into Your Application Server The command-line tools are used for loading suggestion items into the AC back-end. The returned suggestions are displayed as a list attached to the search field. It detects pauses in typing and issues queries to the back-end as the user keeps typing. The AJAX attaches to any existing HTML search form. The back-end consists of a special Solr schema suitable for fast retrieval of partial words and phrases. How it WorksĪC consists of a Solr-powered back-end, the AJAX/JavaScript front end, and command-line tools. At the same time, core functionality is available out-of-the-box, too - just send your queries to dismax_ac handler without advanced parameters. Different combinations are achieved by sending different sets of parameters to your dismax handler (more about the parameters in later sections).
#Solr typeahead how to#
The example solrconfig.xml shows how to configure one simple dismax handler to provide all these functionalities.
For instance, if a person enters “new”, the phrase “new york” would be pushed above “newton”.

Suggestions grouping by a field – for instance, the first 2 suggestions could be sponsored, and the rest unsponsored or the first 5 suggestions could be book titles, followed by 4 dvd titles, with 1 cd title at the end, assuming you have these 3 types of items and their titles loaded into AC.Automatic misspelling correction – if you type “washeng” or “vashin”, both incomplete misspellings of “washington”, AC will offer suggestions like “washington” or “washington times”.AutoComplete in Distributed Environment.Installing AC into Your Application Server.For example, if you type "bass" AC might offer suggestions that include "bass fishing" or "bass guitar", and even "sea bass" (note how "bass" is not necessarily the first word) Contents One can then easily pick one of the suggestions or continue refining the suggestions by typing in more of the query. As one starts to enter search terms, the module detects a pause in typing and offers a list of suggested searches. The AutoComplete ( AC) enhances the search experience through suggest-as-you-type and auto-complete functionality built into the search form.
