I can't seem to get the search function to work very well. I type in the words like "oiled air filters" and set the time frame to newer than 4 years, but it does not bring anything up. Any other tips to make it work? Surely they must have discussed "oiled air filters in the last 4 years. It seems to bring up anything with "oiled", "air" and "filters". How do we get it to reach just the combination of the three words? Thanks.
