• How can I get DocId when adding a document in Lucene index?

  - by Rohit

  I am indexing a row of data from database in Lucene.Net. A row is equivalent of Document. I want to update my database with the DocId, so that I can use the DocId in the results to be able to retrieve rows quickly. I currently first retrive the PK from the result docs which I think should be slower than retriving directly from the database using DocId. How can I find the DocId when adding a document to Lucene?

• How do I rename a process on Linux?

  - by jemfinch

  I'm using Python, for what it's worth, but will accept answers in any applicable language. I've tried writing to /proc/$pid/cmdline, but that's a readonly file. I've tried assigning a new string to sys.argv[0], but that has no perceptible impact. Are there any other possibilities? My program is executing processes via os.system (equivalent to system(3)) so a general, *NIX-based solution using an additional spawning process would be fine.

• Is is possible to create a factory class in PHP?

  - by user198729

  Like the BeanFactory in java: In the much more common case where the BeanFactory itself directly creates the bean by calling its constructor (equivalent to Java code calling new), the class attribute specifies the class of the bean to be constructed. In the less common case where the BeanFactory calls a static, so-called factory method on a class to create the bean, the class attribute specifies the actual class containing the static factory method. Note:it's not the factory method
