| index-dir | none | The location of the index directory. This parameter is
mandatory. Up to 1.9, this parameter called "indexDir" | 1.0 |
| use-compoundfile | true | Advises lucene to use compound files for the index
files. | 1.9 |
| min-merge-docs | 100 | Minimum number of nodes in an index until segments are
merged. | 1.9 |
| volatile-idle-time | 3 | Idle time in seconds until the volatile index part is moved
to a persistent index even though minMergeDocs is not
reached. | 1.9 |
| max-merge-docs | Integer.MAX_VALUE | Maximum number of nodes in segments that will be merged.
The default value changed in JCR 1.9 to Integer.MAX_VALUE. | 1.9 |
| merge-factor | 10 | Determines how often segment indices are merged. | 1.9 |
| max-field-length | 10000 | The number of words that are fulltext indexed at most per
property. | 1.9 |
| cache-size | 1000 | Size of the document number cache. This cache maps uuids to
lucene document numbers | 1.9 |
| force-consistencycheck | false | Runs a consistency check on every startup. If false, a
consistency check is only performed when the search index detects
a prior forced shutdown. | 1.9 |
| auto-repair | true | Errors detected by a consistency check are automatically
repaired. If false, errors are only written to the log. | 1.9 |
| query-class | QueryImpl | Class name that implements the javax.jcr.query.Query
interface.This class must also extend from the class:
org.exoplatform.services.jcr.impl.core.query.AbstractQueryImpl. | 1.9 |
| document-order | true | If true and the query does not contain an 'order by'
clause, result nodes will be in document order. For better
performance when queries return a lot of nodes set to
'false'. | 1.9 |
| result-fetch-size | Integer.MAX_VALUE | The number of results when a query is executed. Default
value: Integer.MAX_VALUE (-> all). | 1.9 |
| excerptprovider-class | DefaultXMLExcerpt | The name of the class that implements
org.exoplatform.services.jcr.impl.core.query.lucene.ExcerptProvider
and should be used for the rep:excerpt() function in a
query. | 1.9 |
| support-highlighting | false | If set to true additional information is stored in the
index to support highlighting using the rep:excerpt()
function. | 1.9 |
| synonymprovider-class | none | The name of a class that implements
org.exoplatform.services.jcr.impl.core.query.lucene.SynonymProvider.
The default value is null (-> not set). | 1.9 |
| synonymprovider-config-path | none | The path to the synonym provider configuration file. This
path interpreted is relative to the path parameter. If there is a
path element inside the SearchIndex element, then this path is
interpreted and relative to the root path of the path. Whether
this parameter is mandatory or not, it depends on the synonym
provider implementation. The default value is null (-> not
set). | 1.9 |
| indexing-configuration-path | none | The path to the indexing configuration file. | 1.9 |
| indexing-configuration-class | IndexingConfigurationImpl | The name of the class that implements
org.exoplatform.services.jcr.impl.core.query.lucene.IndexingConfiguration. | 1.9 |
| force-consistencycheck | false | If setting to true, a consistency check is performed,
depending on the parameter forceConsistencyCheck. If setting to
false, no consistency check is performed on startup, even if a
redo log had been applied. | 1.9 |
| spellchecker-class | none | The name of a class that implements
org.exoplatform.services.jcr.impl.core.query.lucene.SpellChecker. | 1.9 |
| spellchecker-more-popular | true | If setting true, spellchecker returns only the suggest
words that are as frequent or more frequent than the checked word.
If setting false, spellchecker returns null (if checked word exit
in dictionary), or spellchecker will return most close suggest
word. | 1.10 |
| spellchecker-min-distance | 0.55f | Minimal distance between checked word and proposed suggest
word. | 1.10 |
| errorlog-size | 50(Kb) | The default size of error log file in Kb. | 1.9 |
| upgrade-index | false | Allows JCR to convert an existing index into the new
format. Also, it is possible to set this property via system
property, for example: -Dupgrade-index=true Indexes before JCR
1.12 will not run with JCR 1.12. Hence you have to run an
automatic migration: Start JCR with -Dupgrade-index=true. The old
index format is then converted in the new index format. After the
conversion the new format is used. On the next start, you don't
need this option anymore. The old index is replaced and a back
conversion is not possible - therefore better take a backup of the
index before. (Only for migrations from JCR 1.9 and
later.) | 1.12 |
| analyzer | org.apache.lucene.analysis.standard.StandardAnalyzer | Class name of a lucene analyzer to use for fulltext
indexing of text. | 1.12 |
