SOLR to replace native Lucene

Use SOLR indexes instead of the current Lucene implementation.

Benefits:

Scalability
Native Spatial search support instead of using GeoTools
Possibly the OR queries of alphanumeric & spatial search criteria can be resolved (required for CSW compliancy)

Challenges:

Multilingual indexing and search
Spatial operators support. Verify if all spatial operators provided by GeoTools are also available in SOLR.

Solr rough solr based spatial query then Java filter with our implementation
Multilingual support
We will have 1 doc per md doc and multiple field per language.
dynamic field based search to search across all languages
Search Suggestions
Hierarchical Faceting
Error detection
flag any MD that failed indexing or had problems during the process
Search response must be very fast if faceting slows it down then do a second faceting search
Statistics
camel routing for putting into another solr instance for stats
or AnalyticsQuery API
Must be FAST
in memory maybe use metrics?
periodic snapshots in storage? SOLR, database?
