Within X words vs or search

Can someone point me to a help guide that explains how the OR search operator differs from the Within X words search operator? Also, how does one search with AND then further control the span of words of the search? I have tried searching in the guides online but cannot find anything.

Can someone point me to a help guide that explains how the OR search operator differs from the Within X words search operator?

And the relationship of a logical operator to a proximity operator is???

Note that the logical or is either or both - the bold text from the search panel translates the operator into English. You did to work with these until they are as automatic as + and - in arithmetic.

how does one search with AND then further control the span of words of the search?

Parenthesis work exactly as they do in arithmetic and algebra. Am I correct in assuming that since you have worked on an advanced degree that your high-school education was a standard college-prep education? For me to get a sense of what you know/don't know, go to Truth Tables Practice Problems With Answers | ChiliMath, Can you easily solve these problems?

Watch through a few of these videos and see if this helps clear it up for you...

I was never taught about proximity operators. From what I am reading proximity operators are similar to Boolean search operators. This was helpful but I thought Logos possibly did it different. https://www.linkedin.com/advice/0/what-difference-between-proximity-operators-t9laf Thanks Roy. Those are helpful.

Yes. I took Algebra 1 and 2, geometry, business math and science math. I college I did College Algebra and Scientific Math

We never did truth tables. I do not know how to do those. I had a 22 in ACT on Math.

In college algebra I had to do these sections.

Module 1 - Real and Complex Numbers

• Identify the subgroup of Real numbers a number belongs to.

• Identify the subgroup of Complex numbers a number belongs to.

Apply the properties of Real numbers to simplify large expressions.

• Generalize the properties of the Real numbers to Add/Subtract/Multiply/Divide Complex numbers.

Module 2 - Linear Functions

• Construct linear functions using various information about the function.

• Translate between different forms (Point-Slope, Slope-Intercept, Standard) of a linear function.

• Translate between representations (equation, graph, description) of a linear function.

• Solve linear equations.

Module 3 - Linear Inequalities

• Translate between a written description and interval notation for linear inequalities.

• Convert between linear inequalities, graphs of linear inequalities, and their interval notation.

• Solve linear inequalities.

Module 4 - Quadratic Functions

• Construct quadratic functions using various information about the function.

• Translate between representations (equation, graph, description) of a quadratic function.

• Translate between different forms (Vertex, Standard, and Factored) of a quadratic function.

• Solve quadratic equations.

Module 5 - Radical Functions

• Identify the domain of a radical function.

• Translate between representations (equation, graph, description) of a radical function.

• Solve radical equations

In Scientific Math we had this to do.

proximity operators are similar to Boolean search operators

No, Boolean search operators act on sets. Proximity operators apply to specific instances and a simply measures of proximity ... A within a defined distance (proximity) to B. BEFORE, AFTER, WITHIN, NEAR with units of words or characters are the natural language proximity measures available in Logos. You need to take a simple search such as Jesus BEFORE 1 WORD Christ and try variations on "Before 1 word" changing the operator, the number, and the unit until you actually burn into your brain what to expect ...

No I do not know how to do truth tables. I think I mentioned that above. Where should that have been taught at in my college classes above? Thanks for the clarification. I am going to work through the suggestions you gave. Thank you very much.

No I do not know how to do truth tables.

Okay, based on my grandsons (aged 24 and 30) I simply assume that that generation was taught truth tables in either geometry or algebra II. My Google search for online training on truth tables confirmed it. My expectations were incorrect. I wonder where else I have made incorrect assumptions regarding basic skills.

That is the wrong question! A Proximity operator (WITHIN, NEAR, Etc) requires both terms/words to be present e.g. x WITHIN 1 WORDS y requires both x and y to be present, in any order. So WITHIN is similar to the AND operator except that there is no constraint on proximity with the latter. BEFORE, AFTER operators impose further constraints i.e. order.

Also, how does one search with AND then further control the span of words of the search?

Hopefully, you now understand that you must use WITHIN to control the span of words.

A lot of users have trouble with boolean operators when several terms/words must satisfy a condition. For example, they think that "x and y have to be near z", so they start typing x AND y. Unfortunately, AND requires both to be present in the same span of words. The logical requirement, however, is that one or both should be present in the same span, and that requires x OR y.
To complete the query many will use x OR y NEAR z. But there is a precedence of operators such that AND and Proximity operators are executed before OR. So it will parsed/executed as x OR (y NEAR z), where parentheses indicates the preference. To avoid that use (x OR y) NEAR z.

I learned about truth tables in a discreet math class in the computer science department. It included a section on logic.

It's a pretty easy concept. Here's a video that explains truth tables:

Thanks Dave. That explains a lot of what I was missing in my search strategy. It was very flawed and illogical. Rosie, I never took Discrete Math. I did have a Philosophy class with a module section on Logic. That topic was not covered in the class but the video you linked above helped me. I have bookmarked this post to my PC. Thanks again everyone.
