| # System Requirements | |
| Apache Lucene runs of Java 7 or greater. When using Java 7, be sure to | |
| install at least Update 1! With all Java versions it is strongly | |
| recommended to not use experimental `-XX` JVM options. It is also | |
| recommended to always use the latest update version of your Java VM, | |
| because bugs may affect Lucene. An overview of known JVM bugs can be | |
| found on http://wiki.apache.org/lucene-java/JavaBugs. | |
| 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.* |
