Strigi desktop search (2006) implementation was very powerful (http://en.wikipedia.org/wiki/Strigi http://en.wikipedia.org/wiki/Strigi). It was possible to search through an compressed archive inside an compressed archive - in a memory and space efficient way -> "streaming". Strigi uses the Jstream C++ library which allows for deep indexing of files. See this slides from 2006: http://www.vandenoever.info/software/strigi/akademy2006.pdf http://www.vandenoever.info/software/strigi/akademy2006.pdf . The CLucene (C++ port of Java Lucene) also uses the Jstream library (http://sourceforge.net/projects/clucene/ http://sourceforge.net/projects/clucene/). Jstream works similar to the Java "InputStream". Given the discontinued status of Strigi and CLucene, it would be great if one would maintain the Jstream C++ library. Or take its ideas and implement it in zindex.
