The issue with searching for a terms like:
etc - words that are VERY common on this forum by no stretch of the imagination, when standing by themselves, will come up and say:
The following words in your search query were ignored: astro spectra.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards.
This is not because search is blocked, or that we are trying to keep you from finding information that has been posted in the past. Here is a couple of reasons I can think of why this is an issue:
1) Use of system resources. If there are 20 users searching words like astro spectra - it has to keep track of those individual searches across all 20 users, and where the user is in reviewing the results. If it returns over 50,000 posts - do the math out. It does take a lot of resources to do that.
2) Even if it returned all 50,000 hits, the chances of you actually looking at 50,000 posts - is very very small.
You can perform a search like astro spectra cps. It will tell you it ignored astro spectra, but found you a bunch of hits based on cps. But, instead, think of what you want to know about astro spectra cps.... You really want to know about issues with talkgroups. So, place the word talkgroups in the "refine" search, and run the query again. You will notice that in this result set, astro and spectra show up in the hits as well.
While it's not the best for someone who is just looking to casually browse, thinking about the issue, wording your queries correctly, will yield the best results. I also suggest you read up on the help or other screens built in to the board should you have further questions, or use advanced search to further filter the responses you are looking for. You may not need to see hits on a portable radio - where it may have been mentioned in Vehicle Installs, for sale, and feedback related forums.
Give it a shot.
