Apache Lucene runs of Java 7 or greater, Java 8 is verified to becompatible and may bring some performance improvements. When usingOracle Java 7 or OpenJDK 7, be sure to not use the GA build 147 orupdate versions u40, u45 and u51! We recommend using u55 or later.It is also recommended to always use the latest update version of yourJava VM, because bugs may affect Lucene. An overview of known JVM bugscan be found on http://wiki.apache.org/lucene-java/JavaBugsWith all Java versions it is strongly recommended to not use experimental`-XX` JVM options.
CPU, disk and memory requirements are based on the many choices made in implementing Lucene (document size, number of documents, and number of hits retrieved to name a few). The benchmarks page has some information related to performance on particular platforms. *To build Apache Lucene from source, refer to the `BUILD.txt` file in the distribution directory.*
