No, the search engine is not case-sensitive. For example, a search on "REPORT" will also return pages containing "Report" or report. A search on "deed" will also return pages containing "DEED".
Yes, the search engine checks your search words against all of the words collected from the web site. When a word appears to be misspelled, the search engine looks at all the words it knows and offers you a word that could replace it.
Boolean operators must be typed in UPPER CASE or they will not be recognized as operators.
The Boolean operators 'OR', 'NOT', '-', and '+' may be used in your query.
Using 'AND' is not necessary since all words are searched by default.
The asterisk '*' can be used as a wildcard character.
Boolean Operator
Description
OR
Use 'OR' when you require only one of the search words to appear in the results. Example: "city OR county"
NOT or -
Use 'NOT' or '-' when you do not want to exclude results that contain a particular term. Examples: "economic development NOT support" or " economic development -support "
*
Use '*' as a wildcard to search on all words that contain the letters you enter. You must enter a minimum of three letters plus the '*' character. Example: "employ*" would find "employ" or "employer" or "employee"
+
Use '+' when you require the exact word to appear in all of the results. For multiple words, you must use put a + sign in front of each word that must be exact. Example: search on "+lipitor cholesterol" if you only want to retrieve results with the brand name "Lipitor" and the word "cholesterol", and no results with the generic synonym "Atorvastatin"
There are a few reasons why you could have received this message:
Your word may be misspelled and the search engine can't find a substitute for it. For example, if you had typed in "metakare" when you meant "medicare", the search engine won't be able to recognize it.

A number of countries have incorporated precast components in bridge superstructures and substructures. Precast components include deck, abutment, and wall elements. Benefits of using precast elements in bridge construction include the high level of ...
MnDOT used the phased array ultrasonic testing (PAUT) system to conduct corrosion mapping on steel bridges. The system provided more accurate corrosion data than did single-beam ultrasonic testing and traditional field measuring methods. More ...
Roughly 20 percent of MnDOT's inventory of anchor bolts for sign structures, light towers and traffic signals may be loose at any given time. Researchers examined specifications and procedures for tightening anchor bolts in Minnesota, and conducted ...
The Minnesota Department of Transportation (MnDOT) funded two projects in an effort to mitigate anchor bolt connection loosening and develop improved pre-tensioning steps for its sign, luminaire, and traffic signal (SLTS) structures. The Phase I ...
Because of a growing concern about the overall safety of pedestrian bridges, investigators used laboratory studies and computer simulation to gauge their ductility, strength and stability as compared with AASHTO specifications. Results showed that ...
Self-compacting concrete offers significant cost benefits in precast girder construction, but performance testing and mix design standards were needed to enable use of SCC in Minnesota. Researchers evaluated wet-state performance of a range of ...
Design specifications of shear reinforcement requirements in prestressed concrete bridges have changed significantly. Researchers load-tested to failure a girder that was built to older design codes and evaluated its shear capacity. They also ...
Investigators studied the effectiveness of a new design for short-span bridges, monitoring and analyzing bridges in the field and in the laboratory, paying special attention to the development of cracking in the deck above the joints of the bridge.
This project implements research that classifies steel bridges based on the frequency and severity of fracture and fatigue-sensitive details that are present in each bridge. The gross ranking of bridges with high, medium or low need for preventive ...
The objective of this project was to conduct vibration testing of dowel laminated timber bridge systems to better understand the potential for using vibration testing to assess the structural health and condition of bridges in Minnesota. A second ...
