Lucene performance using a solid state disk (SSD)

Has anyone done any benchmarking of Lucene running with the index stored on a SSD? Given the performance characteristics quoted for, say, the SANDISK devices (eg http://www.sandisk.com/OEM/ProductCatalog(1321)-SanDisk_SSD_SATA_5000_25.aspx: 7000 IO/sec for 512 byte requests, 67MB/sec sustained re

Re: Payloads and PhraseQuery

I have a question about the way fields are analyzed and inverted by the index writer. Currently, if a field has multiple occurrences in a document, each occurrence is analyzed separately (see DocumentsWriter.processField). Is it safe to assume that this behavior won't change in the future? The reas

Size of field?

Hi guys, I would like to know if exist some limit of size for the fields of a document. I'm with the following problem: When a term is after a certain amount of characters (approximately 87300) in a field, the search does not find de occurrency. If I divide my field in pages, the terms are found

Actually no, Because I'd like to retrieve terms that were computed on the same instance of Field. Taking your example to ilustrate better, I have 2 documents, on documentA I structured one field, Field("fieldA", "termA termB", customAnalyzer). On documentB I structured 2 fields, Field("fieldA",
