Hi David,
How can I use these term operations via the terminal of Ubuntu? What directory I should be in?

For example, I'm currently in the indri-5.11/ directory.
What command should I run to get the results for #uw"3"(blue car)?

Thanks :)

Regards,
Aarjavee.

Terms are the basic building blocks of Indri queries. Terms come in the form of single term, ordered and unordered phrases, synonyms, among others. In addition, there are a number of options that allow you to specify if a term should appear within a certain field, or if it should be scored within a given context. Term Operations in the Indri Query Language: Name | Example | Behavior -----| ----- |----- term | dog | occurrences of dog (Indri will stem and stop) "term" | "dog" | occurrences of dog (Indri will not stem or stop) ordered window | \#od''n''(blue car) -**or**- \#''n''(blue car) | blue ''n'' words or less before car unordered window | \#uw''n''(blue car) | blue within ''n'' words of car synonym list | \#syn(car automobile) | occurrences of car or automobile weighted synonym | \#wsyn(1.0 car 0.5 automobile) | like synonym, but only counts occurrences of automobile as 0.5 of an occurrence any operator | \#any:person | all occurrences of the person field
