Musings and Other Things from CF Guru Mark Kruger: Troubleshooting and Optimizing Solr on ColdFusion 9. Passing a query object to the CFINDEX tag is great for building an index from scratch setting my table’s “productName” as the document title. Railo uses Apache Lucene, and ColdFusion uses Solr (which in turn uses if you like) * / will delete the current collection * / so .

Populates a search engine collection with metadata and creates indexes for searching it. The engine Solr can search physical files of various types or a database query.
Indexing database columns that result from a query lets users search the query data much faster than they could if you used multiple SQL queries to return the same data. You also can index a collection using the ColdFusion Dolr. You can specify this tag’s attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag’s attribute names as structure keys.
If yes, automatically commit the changes to the search co,dfusion. By default, the value is set to true. Name of a collection ineex is registered by ColdFusion; for example, ” personnel “.
A string value that specifies one or more search categories for which to index the imdex. You can define multiple categories, separated by commas, for a single index. If you use a query for your indexed data, this value can be the name of a column.
A string value that specifies a hierarchical category or category tree for searching. You can specify only one category tree. Use to coldfuskon discrete values in collection records, which lets you search for specific records. By contrast, values specified in the body attribute are concatenated and searched as a body of text using the specified criteria.
Coldfusion CFSEARCH: indexing SQL data with Solr – Stack Overflow
Oslr, ColdFusion 10 added support for dynamic custom fields. For example, the following code returns files with a listed extension or no extension: Boost specific fields while indexing. Multiple fields can be boosted by specifying the values as a comma-separated list. The key attribute is the name of a column in the query that contains a full filename including path.
The extensions and recurse attributes, if specified, elaborate on which files are included. If the action is delete, cfindex deletes keys for the collection. The key attribute specifies a column name that contains anything you want; for example, the primary key value in the database.
It must be unique because this is the primary key in the collection. If the action is delete, the key attribute is the name of a column in the query that contains the keys to delete. The body attribute is required and is a comma-delimited list of the names of the columns that contain the text data to be indexed. The extensions and recurse attributes, if specified, designate which types of files are included. If the action is delete, both the keys and the document files are deleted.
The key attribute is an identifier that specifies the key. If the action is delete, the key attribute is the document key to delete. This allows you to change a field to empty in the collection.
A structure coldfusikn keys with diagnostic messages about the indexing of these keys. If there are coldrusion bad keys, this key does not exist. An array of diagnostic messages, coldfksion nonfatal errors and warnings. If there are no messages, this key does not exist. Added the parameter throwOnError.
Added new actions fullimportdeltaimportstatus, abort. Added the attributes autoCommit, fieldBoostdocBoost. Added support for dynamic custom fields. Added Solr search engine support. Removed reference to external collections.
ColdFusion automatically detects whether a collection is internal or external. Changed Verity operations behavior: Changed acceptable collection naming: Changed query result behavior: Removes collection documents as specified by the key attribute.
Deletes all of the documents in a collection. Causes the collection to be taken offline, preventing searches. Deletes all of the documents in a collection, and then performs an update. To index full database. For instance, when you index the database for the first time. For instance, for any updates in the database, instead of a full import, you can perform delta import to update your collection.
Provides the status of indexing, such as the total number of documents processed and status such as idle or running. Aborts an ongoing indexing task. Changes to the search server. Given multiple collections, merge them into a single collection. Re-organizes all segments in a core to a single segment.
Solr enhancements in ColdFusion 10
Optimization is operationally time consuming, and is not advisable if the index changes frequently. Solr reads a copy of the entire index and restructures the copy into a single Segment, resulting in a much slower operation. For more information, see Optimizing Solr Performance. You can specify columns in a delimited list, indeex example: If not a query, an identifier such as the URL for a web page, for example.
Null The name of the query coldufsion which the collection is generated. Expects a filename in the key attribute. Applies action to files in a directory path that pass the extensions filter. Expects a directory name in the key attribute. Used for Data Import Handler. Type Attribute values File The key attribute is the name of a column in the query that contains a full filename including path.
Path The key attribute is the name of a column in the query inde contains a directory pathname. Custom The key inddx specifies a column name that contains anything you want; for example, the primary key value in the database. Type Attribute values File The key attribute is required and is a full pathname to a file. Path Coldfuison key attribute is required and it is a directory pathname. Custom The key attribute is an identifier that specifies the key. The body attribute is required and is the text to be indexed.
Comma-separated values of collection names. Colcfusion text to index. The value specified for key depends on the type attribute: If true, then cfindex tag throws an error while indexing documents. The key attribute is the name of a column in the query that contains a directory pathname.
