Users in this situation are advised to consider the complexity of their queries/configuration, and increase the value of maxBooleanClauses if warranted.Ītomic/partial updates to nested documents now require the _root_ field to clearly show the document isn’t a root document. Users who upgrade from prior versions of Solr may find that some requests involving complex internal query structures (Example: long query strings using edismax with many qf and pf fields that include query time synonym expansion) which worked in the past now hit this limit and fail. Solr.xml maxBooleanClauses is now enforced recursively. Highlighting: hl.method=unified is the new default. Values serialized in this way will need to be updated accordingly. Wrapped in a element at the top level of each (or within an enclosing Obscuring associated field names and yielding inconsistent structure. Previously, values were dropped in directly as top-level child elements of each , The response format for field values serialized as raw XML (via the raw value DocTransformerĪnd wt=xml) has changed. The legacy behavior of expanding the expr parameter can be reinstated with -DStreamingExpressionMacros=true passed to the JVM at startup MacroExpander will no longer will expand URL parameters inside of the expr parameter (used by streaming expressions).Īdditionally, users are advised to use the InjectionDefense class when constructing streaming expressions that include user supplied data to avoid risks similar to SQL injection. The computation of stdDev and variance in JSON aggregation is same as StatsComponent.įacet count in Json Facet module always returns a long value, irrespective of number of shards. JSON aggregations uses corrected sample formula to compute standard deviation and variance. Existing Solr configurations do not need any SQL related changes, however the module needs to be installed - see the section SQL Query Language. SQL support has been moved to the sql module. A request can be modified via the standard distrib=false param to only use the local core receiving the request. Users/apps may be assuming the old behavior. Implicit /terms handler now returns terms across all shards in SolrCloud instead of only the local core. New snowball stemmers: Hindi, Indonesian, Nepali, Serbian, Tamil, and Yiddish.
